Sage 50 Accounts – Error: Username is in use – the program cannot connect you at this time

Did your entire computer or Sage 50 Accounts crash on you? Perhaps one of the annoying Windows updates restarted your computer whilst Sage Accounts was open? Now you try and launch Sage Accounts, enter your username and password (or the default username of manager) and it gives you an error stating:



Username is in use – the program cannot connect you at this time

Your only option is to click OK which isn’t very helpful. Even after a full system reboot the same thing happens. Note that I use Sage 50 Accounts Plus 2011 (v17) but I’ve had the same thing happen before in Sage 2010, 2007 etc and the principal behind the fix hasn’t changed so give it a try.

After half an hour on the phone to Sage support, there is a very simple solution:

  1. Click on Start–>My Computer
  2. Double click on the C:\ drive or which ever drive letter has your \Documents and Settings\ folder on and double click to go into the \Documents and Settings\ folder
  3. Double click to go into the \All Users\ folder
  4. Double click to go into the \Application Data\ folder
    [if you can’t see an \Application Data\ folder and the first in the list alphabetically is \Desktop\ then you need to click on Tools in the menu bar, the Folder Options, then click on the View tab and look in the list for “Show hidden files and folders” and select this option, then you should be able to see the \Application Data\ folder although it might look feint or greyed out.
  5. Once in the C:\Documents and Settings\All Users\Application Data\ folder scroll down and then double click on \Sage\ folder
  6. Double click to go into the \Accounts\ folder
  7. Then depending on when you first setup the account click to go into that year, in my case I have a \2010\ and a \2011\ folder but my data is in the \2010\ folder so double click to go into the year.
  8. You should then see a \Company.000\ folder, I assume that if you have a license for multiple company accounts there may be several of these, one for each company accounts but in my instance I have a single user and single company licence so I just have one \Company.000\ so click to go into that
  9. Once in \Company.000\ click on the \ACCDATA\ folder
  10. Nearly there…. I am now in the following directory:
    C:\Documents and Settings\All Users\Application Data\Sage\Accounts\2010\Company.000\ACCDATA\
  11. There will be lots of files with a .dta file extension in here, simply scroll down to until you see QUEUE.DTA and select it.
  12. At this point you could (but don’t)  just delete QUEUE.DTA as this is the file that is locking you out from Sage and will be recreated when you next login and no company information will be lost at all. But rather than just deleting the file, it is better practice to rename this file to something different so that if it does break something, you can rename it back to the original and no harm is done.
  13. Right click on QUEUE.DTA and choose rename.
  14. Type in a new filename, in this case I’ll rename it to QUEUE.DTA.OLD and hit enter.
  15. Now try logging into Sage Account again and you should be all fixed.

  1. Thank you for the information it helped.
    Best way to find the QUEUE.DTA is to do a search on your C drive for this name and leave it running it will come up with the file and you go and rename it.

    I tried the path given here and managed to come to the Sage \ Accounts but could not find the file. Mind you my sage 50 is 2013 version.

    Best of luck for anyone with similar problem.

  2. Hello, can anyone help me? SAGE 50 HR closed down unexpectedly then rebooted computer and when try to open it up, doesn’t ask for my username or password and just ‘The company is currently in use by another user’ but no-one else has SAGE open.

  3. Thank you so much! I had just spent literally hours doing something in Sage I had never done before, then carefully pressed Back Up then— PC crashed. You made this so easy — a million thanks

  7. Thank you soooooo much! Found your solution whilst waiting an estimated 15 minutes for the Sage helpdesk. All fixed, and I hung up before my call was answered ….. think I’ll cancel my Sage support!!


  9. This problem has occurred with a customers V8.02 the information re the offending file is correct but the location is wrong its in Program files\sage.
    The easiest way to find & either delete or change is to use Search & change it there.
    Many thanks for the file name

  10. I have just had this issue on a windows 7 machine, as the file structure is slightly different, I searched for the file and found it at this location. I renamed the file and it worked a treat. thank you for this tip



  11. Hi, I’m running V 11.2 Sage Instant Accounts on Win 7. When I closed the business 3 years ago, it was running on Win XP and so the ‘queue.dta’ ‘fix’ – as above – worked every time. Unfortunately, my accountant needed some reports as the taxman is querying something and, on running the .pdf report, he got ‘locked out’. I tried doing the ‘fix’, but no go. The ‘queue.dta’ file is still deleted, but I still get locked out with the error message. Could this be something to do with the fact that it’s running over Win 7 and not Win XP?
    Any help very much appreciated, thanx

  12. Try and download ” Long Path Tool ” is also useful in situations where you see these error messages: Cannot read from source file or disk, there has been a sharing violation, cannot delete file or folder, the file name you specified is not valid or too long, the source or destination file may be in use and many other file managing errors.

  13. Woohoo! Life saver! Nice little quiet time between Xmas and the New Year, turned into a complete waste of time until I found this page! You’re a star. Happy New Year!

  14. Thank you thank you – I’ve spent all evening working on a new client and it crashed due to power failure. This worked.

  17. Awesome article!! Felt compelled to leave a message to say thank you for such clear step by step instructions. Worked a charm.

  18. Thankyou so much for the tips on Sage Instant Accounts, I do my hubbys accounts on a saturday, Sage are not there on the phone and the website was down for maintenance – such a life saver!

  19. I am using Sage instant accounts v12.00 in a virtual windows environment on my Mac and have the same problem. Initially the program hangs when started and indicates it is “not responding”. After quitting the program I get the same error message when reopening.

    I have tried the above to no avail. Uninstalled and reinstalled the program and also copied the QUEUE.DTA file from a working version on my laptop but nothing seems to work.

    Anybody got any other suggestions?

  20. Thanks for this! It just got me out of trouble with my copy of Sage Instant Accounts that had thrown its tows out of the pram.

    As other comments suggest, the location of queue.dta may vary so I suggest people do a simple search to locate the file and rename it.

  21. Hi I am using sage v8.2 and yes a windows update occured and shut my computer down when sage was open.
    I am familiar with the queuedta file deletion method, however when I go to the sage folder and then the accounts folder it says file empty whereas usually I get my list of files up which when I scroll down the queuedta folder is there – any suggestions

  22. The technique of deleting the QUEUE.DTA file is fine but the location varies!

    It does not have to be where you said. This is the default for V2010 but for network users, people who have upgraded or are installed on Vista+ operating systems this is not always going to be correct.

    I have a little guide/tool here that will help you find it if it is not in the default location.

    For Darryl the solution is to “reindex” and then “compress”, these are in File>Maintenance>

  23. I use sage too. I have a really weird problem where the latest sales order or quote entered does not appear on the sales order list or the quotations list. When you enter a new SO or Quote, the one that was previously missing appears as the latest on the list?!! I have tried Sage support on this, but they say it must be a data issue, and aren’t that helpful about it, as it isn’t a know issue. Saw this article of yours when I googled the problem, and wondered if you might have any ideas, please? Thanks!

  24. Hi. The solution might work with earlier virsions but in Sage 50 2011 the path is C:\Documents and Settings\All Users\Application Data\Sage\Accounts\2011\Practice. If u try to rename QUEUE.DATA AS QUEUE.DATA.OLD- it will ask the file might become unusable if you rename it.
