Launcher won't start

in Game Support
Hello,
I have a problem with launching the game. It played just fine a couple of months ago and I got some 100 hours on it without an issue. I reinstalled it last night and now I can't seem to start it; when I click play on Steam I get the AA's logo, the game window opens as if it is about to launch, but all I get is a white screen that then disappears after some 2 or 3 seconds without an error message. Since there is no message I am not really sure what to do next, I already tried reinstalling the game, restarting the PC and Steam with no result.
