Install the game, run it and it worked fine. Then try to run it again and it just doesn't start, in the task manager it shows running but never starts.

Are you using Galaxy? If so, try running the executable from the install folder bypassing Galaxy completely and see if that works. It seems that the recent update to Galaxy has prevented a few games from starting.

Thank you for your answer, it seems that the problem is the patch that increases the resolution. I guess some change is recorded in the registry because not reinstalling the game works.
