After B&W got installed I can't play TW3 anymore! Tried starting it through GOG and through TW3's launcher and nothing. Game start to load for a couple of seconds and then stops... Come on GOG WTF?

When I click on TW3 .exe for the second time I get "Game is already running" message but Task Manager shows nothing...

BTW I can't be sure if it 's B&W or patch 1.20 that is the cause.

Scratch this. Needed to verify my files and all is well again :)

You had an itch and found it,congrats:-)
