Steam issues with Poker Night 2

So I run a Windows 8 machine with a 560 gtx but every time I got to start this game, nothing happens. No crash message, nothing showing on the task manager, or any indication that it's no starting. If I try to click the play button again shortly after that it does say that the game is already running but that's not even the case. I've already deleted and reinstalled 3 times. Any help would be appreciated. Thanks
