You can only sign into one workstation with your user name, not two simultaneously.  I would suggest adding a user license if this is an issue.

Hi, Thanks for replying. We never sign in to both workstations simultaneously. But the both do not open now, each one on its own. 

Any more help here?

Your problem sounds similar to ours but on a smaller scale. We have 40 users but experienced the same things almost every day. I have found that this solution helps stave off the problem for longer ( about a week or so), it is only a band-aid until sage can actually fix the problem. I apologize if this does not help. I just thought I would offer something that has helped us. 

While I have been researching this issue I have noticed that if you monitor the root company directory. (I.E. sage/peachtree/company) One can see the file SUA00021.lck populate temporarily when a user initially logs into PT. It seems this file is meant to very briefly lock the directory until the user can be placed in the proper store company folder. After the user gets placed, the SUA00021.lck file is should be deleted/removed automatically from the root company directory. Afterward, a .lck file should then be placed in the needed company folder the user is attempting to access locking it so no one else can access while the user is logged in. It seems the problem is the process that is supposed to remove/delete that SUA00021.lck file is not working properly. 

    I have found that closing the SUA00021.lck file, found in "open files" on the server in the "computer management" program will most of the time, allow all users to log in. On occasion the user that populated the SUA00021.lck file, found in "open files", needs to reboot their computer after the open file is closed. If that user continues to create the SUA00021.lck file, you can uninstall their Actian PSQL program and reinstall. 

    To uninstall, you can find it near the top of the program list under "uninstall or change a program" in the control panel. To re-install open the sage installer files and go to the following path:

Sage 50 2020 Disk\PervasiveMin

After doing so run SetupWorkgroup32_x86.exe 

While installing the program, make sure to install it as a service. 

    Hopefully, this helps others that are running into this issue. Please let me know if anyone knows of a permanent solution to this problem. I know that Sage is aware of this and I cannot believe this has not been fixed or addressed. This has cost our company a lot of time and money. We are extremely disappointed in sage and hope there will be a very quick resolution provided by them soon.

Thanks for your help. 

When I looked for open files in the computer management, I did not see any open files to close, but I did see the file you're talking about in the company folder. So I could not try this to see if it's a solution for my issue.

But yes, I am constantly having problems opening Sage50 which is very disappointing and time consuming.
