Failure to start

[alchron]

I just purchased Amnesia the dark decent from steam, and the game refuses to startup. I did try the fixes that were listed for the problem, but nothing will allow me to even get the game loaded up. I am running Win 7 64 bit with an ATI Mobility Radeon HD 5870 card, and have also ran in compatibility mode with Windows XP SP2 and Vista SP2 (all check boxes including running as administrator). The graphics card was updated recently, and I do own Prenumbra which runs perfectly fine as well. Is there something else that can be done?

Was there any error message when you try to start the game?

No, there wasn't any error messages, just it would turn the screen black and then it would go back to the desktop. Sorry it took so long to reply back, with holidays and whatnot. Anyways, I did run a verify files through steam to see if anything has been done, but nothing so far. My big question is whether there is an actual support ticket system from the developers to get in contact with, or if there are actually gonna be any support for those that purchased the game through steam.

What I do find odd is that I can play Prenumbra just fine without any compatibility issues, and I just assumed it was running off the same platform.
