There is a KB article about TeamViewer.  Try disabling QuickConnect.  Here's the link:

I'll give it a try and reply back, thank you.

Well, I imagine it would work if there were not a password on TeamViewer advanced setting on the desktop program.  And I do not have an option for disabling a QuickConnect on my (remote) end of the TeamViewer connection.  (Sigh.)  I guess we'll have to wait for the IT person to assist. 

Thanks, Terry! 

The TeamViewer issue was resolved by them quite a few versions ago.  They had problems with many programs and removed that functionality.

The error detail doesn't tell us enough to be able to help.  The initial wording is what we need, after the "Firebird Database Engine has encountered an error."  The next line of text is critical to resolution.

If you are using Timeslips 2020 (28.0.0.41) and not Premium, you will need help from a certified consultant.  Sage supports Timeslips Premium now, and you would want to install the latest update (30.0.3.71) to it if you are subscribed to it.
