Amnesia pleayed fine when first run but now only shows black screen

[sneff]

I am running a Acer G5900 predator desktop, windows 7 64 bit, with a core I7 870 cpu, 6 gig of ram and a nvidia geforce GT430.

When I first played the game after buying it from the humble bundle it worked fine I was able to play with out glitches or anything like that. I made my way in to the archives section with out any trouble, then saved my game and exited since it was late. Now when I go to load my game i can hear sounds and one time saw sub titles but that is all. no dot for the cross hair can not move or open inventory. I can open the menu to change setting save and exit the game ( that works fine ).

I my drivers are up to date and i have tried the SDL.dll fix. I have also tried resetting the graphics and tried setting them to low.

Any information to help solve this problem would be appreciated
