Check the number of logged in users

To see who's currently logged in, check the user list:

1. Log on to Sage Accounts as MANAGER.
2. Click Settings then click User Management.
3. Select Active Sessions.

NOTE: If you are using a version of Sage 50 Accounts older than v27, you'll find this option under View, then User List. 

Depending on your licence, there's a maximum number of users that can access the software at any one time. If the maximum number of users are already logged on, the message appears when the next user tries to log on.

If the maximum number of users are currently logged in, you must wait until one of these users has logged out before you can access this company. 

If the maximum number of users aren't currently logged in, continue to the Check licence details on all computers section.

Check licence details on all computers

The maximum number of users is determined by the serial number and activation key that you enter in Sage 50 Accounts. This message can appear if one or more of your computers doesn't have the correct activation key.

Do this on every computer that uses Sage 50 Accounts.

1. Click Tools then click Activation and click Upgrade Program.
2. If prompted to ensure that you do this on each station of a multi-user system, click OK.
3. In the Product Registration window, check that the serial number is correct. If you're unsure what your serial number or activation key should be, please contact Sage Technical Support.
4. In the New Key box, enter the current activation key then click Continue.
   • If you receive a message advising that the activation key matches the current activation key or you must enter a NEW product registration key, this means that the correct key has already been entered on this computer. Click OK and click cancel to close the Product Registration window
   • If you receive a message advising that the program has been successfully upgraded, this means that an old activation key had been entered on this computer and you've now entered the correct one. Click OK to close the software

If the message is still appearing after checking this on every computer, continue to the Delete the queue.dta file section.

Delete the queue.dta file

CAUTION: When following this article, if you need to delete any files, you must ensure that you first stop the Data Service or lock Sage Drive.

The queue.dta file stores information about which users are currently logged in and which tasks they're performing. If a user doesn't close the software correctly, for example, if the software crashes, the information in the queue.dta file may be out of date and result in this message appearing.

To delete the queue.dta file:

1. To ensure that the information in the queue.dta file is correct, ask all users to log out of Sage 50 Accounts.
2. Locate the queue.dta file in the ACCDATA folder.

   Open Sage Accounts and logon as usual then click Help and About, then in the Program Details click the path for the Data directory.
