Can't Open My Desktop Version

Getting this error: 19.1.11: System.Net.Sockets.SocketException (0x80004005): Address already in use
at System.Net.Sockets.Socket.Bind

I last opened in April 2020. I don’t want to lose my data. Since it won’t open, I do NOT know what version I have.

You will not lose data. None is stored in the program. Your data is in a separate data file.

You have version 19.1.11. You should update, as you are hundreds of versions behind. See if you can open the program after updating.

Thanks, downloading newest version did the trick! Thanks for the tip Tut!
