Situation
The maximum number of users is already accessing this company file. You can't open this company file at this time.
Solution
Wait until one of the users accessing the company file stops using the company file. If you encounter this message frequently, you may wish to purchase additional workstation licenses to increase the number of simultaneous users of the company file.
The Active Workstations window allows you to see which users are currently accessing a particular company file. This window also shows the number of workstations licensed. To open the Active Workstations window, choose Active Workstations from the File menu on one of the workstations already accessing the company file.
If the number of simultaneous users allowed under your MYOB AccountEdge license has not been reached, it's possible that the company file was closed incorrectly the last time one of the users exited MYOB AccountEdge. To repair this situation, all current users of the company file must close the company file and then reopen the company file. You should then be able to open the company file with this user ID again.
