Check the number of logged in users

Check the user list:

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

Your licence controls how many users can access the software at the same time. The message shows when you reach the user limit and another user tries to log in.

If the maximum number of users have logged in, wait until one of them logs out before you can access this company. 

 TIP: To upgrade the number of users, leave your details and we'll be in touch.

If few than the maximum number of users have logged in, continue to the Check the licence details on all computers section.

Delete the queue.dta file

The queue.dta file stores which users have logged in and the tasks they're performing. For example, if a user doesn't close the software correctly, the information in the queue.dta file can be out of date. This causes the message to appear.

To delete the queue.dta file:

1. Before you start, stop the Data Service or lock Remote Data Access.
2. To ensure that the information in the queue.dta file is correct, all users must log out of Sage.
3. Locate the queue.dta file in the ACCDATA folder.
4. Open Sage Accounts and logon as usual, then go to Help and About.
5. In the Program Details section, click the path for the Data Directory.

If you're unable to open Sage 50 Accounts, browse to the following path for your version:   

C:\ProgramData\Sage\Accounts\20xx.  Where xx is the year of your version. For example, 2026 is v32.

6. Locate and double-click the COMPANY file then choose to open with notepad.
7. Take a note of the relevant path.
8. In Windows explorer, browse to the path noted in step 3, then double-click the ACCDATA folder.
9. Right-click the queue.dta file and click Delete then click Yes.

The software creates a new QUEUE.DTA file the next time you log in to this company.

Check the licence details on all computers

The serial number and activation key you enter in the software sets the maximum number of users. This message can show if any of your computers don't have the correct licence details.

Do this on every computer that uses Sage 50 Accounts.  TIP: If you can't log in on a computer, open Demonstration data to check the licence. 

1. Go to Tools, then Activation, and select Upgrade Program.
2. If prompted to do this on each station of a multi-user system, press OK. 

 TIP: Use our article to find your serial number, key, and account number. 

3. In the Product Registration window, check that the serial number is correct.
4. In the New Key box, enter the current activation key then press Continue.
   • If you see a message that the key matches the current key or you must enter a NEW product registration key, the key already exists. This means that you’ve entered the correct key on this computer. Press OK then Cancel to close the Product Registration window

   • If you receive a message that the software is upgraded successfully, you’ve entered the correct or new key. Press 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.
