I just downloaded the Amnesia demo, to try it out before I considered getting the actual game. 
However, every time I open the game I get a message that says: 
"Amnesia.exe caused an EXCEPTION_ACCESS_VIOLATION in module <UNKNOWN> at 0023:00000000" 
I searched around the internet and really didn't find anyone who could help. Any ideas? 
By the way, my laptop is a Toshiba Satellite with a Mobile Intel® 4 Series Express Chipset Family. 
If there's any solutions, please make them as simple and easy to understand as possible
