Please restart application. Current problem saved to log file

Thank you so much for helping me, how can i check my instance name in sql ?

What’s your connection string?

At least sambapos is running on a laptop in which i could restore my last backup.
But when i try to do the same on the desktop, look what’s happening…
i don’t understand…!

Again what’s you connection string?
Looking at the header of window don’t see SQ suggesting maybe your in testing .txt database mode which would not allow a backup restore.
Show your database connection string.
Do you have SQL express installed?
