I've been having the same problem, I tried everything I have found on any website at all, even stuff that sounds ridiculous.
I have deleted all my saved games, prepared to start over just for a chance to complete episode 2 at some point.
But my game WAS working before, I did play episode 2 until I always got stuck in the barn.
I couldn't leave, and I couldn't open the stall doors, because if I did I could no longer move or do anything.. just stood there. So every time that happened I would restart the game, and that happened a few times until the game stopped working completely.
So. I reinstalled, and now it doesn't work at all.. and like I said, I've tried absolutely everything and I'm not sure what to do anymore..
Also, I tried creating a new account on my computer. Didn't work, either.
EDIT: I'm not using Steam, or Windows 8. I'm on Vista. It's all in Telltale.
