Amnesia Crash

[Catserina2010]

I got Amnesia over a year ago and haven't played it for a while. Back then it worked just fine. I even managed to beat the game (on the same computer I'm using now). Recently I thought I'd go back and play it again. But now it won't work. I can launch the game just fine. But when I try to start a new game, the screen goes white and it looks like it's loading. When I try to continue my previous game it works for a few seconds, but as soon as I try to do anything, it also goes to a white screen and looked like it was loading. I tried uninstalling and re-installing the game, I updated to the latest version, I even tried to lower the graphics setting, just in case. But if it worked before, I don't understand why it isn't working now.

I've spent hours trying to figure this out, so any help would be greatly appreciated!
I run on Windows 7 professional, and I have a HP 64-bit laptop.
