Hi All,
I wanted to upgrade an existing WFA installation from 5.0 to 5.1.
Tried to just upgrade it with installer, dropped this error, after that I cannot login anymore to WFA.

Tired to uninstall completely and reinstall and restore backup file, it starts to restore than suddenly logging out from app, and and again after that I was not able to log back in anymore.

Any suggestion how to solve this?
Man Thanks
Zoli
