Game does not start.

[firefox0402]

Hello Guys

First of all, I am sorry for my english.

2 Days ago I got Amnesia: The Dark Descent from Steam and could it startet without any problems.

Yesterday I tried to start it again, i double clicked it, but nothing happened. Even if i try to start the game directly on Steam, nothing happens. If i click on the "Amnesia-Icon" on the Desktop more often, then a message pops up for about 3 seconds saying "Amnesia: The Dark Descent Loads" (or so), then the message disappears and nothing happens. There isn't even an "error-message" or something else.

I have already reinstalled the game twice, then i enabled the function to start the game as Admin, i've checked directly on Steam for errors. Still nothing.

What could I do?

Thank you ahead

(and once again, I am sorry for my english)
