Game wont start.

[Ziram]

I started playing amnesia few weeks ago started playing the game fine. Then one day when I tried to start the game it wouldn't start. My name comes up green for a few seconds saying im playing the game then goes away. No error screen or nothing. I have tried repairing files, running as admin, reinstalling the game and even reinstalling steam and still the same problem persists only with this game. HELP!
-Thanks
