Hi i just baught the game from Steam. After 8 long hours of waiting for the game to be done, It was finally done, but then the problem came, I can't start the game. The loading box from steam comes up, and then it goes down after 1-2 sec and the game dosent start

I FEEL LIKE IVE BEEN RIPED OFF..... 29.99£ for that .. Not even worth it
