Amnesia The Dark Decent not opening

[CalebPlaysPC]

So I try to open up Amnesia: The Dark Decent and it wont open at all. I click it on steam and it says im playing for like 5 seconds then it goes away. The game doesn't even open up and I cant even see the main menu or the menu screen that pops up before you play. I tried ununstalling steam, uninstalling the game and reinstalling and it wont work! Someone Please help ASAP
