Hm. This is odd. I downloaded it today (it said it'd take 2 days 2 hours but only took about 30 minutes. :P) but when I press play it seems to work but the screen is blank. The noises are all there and stuff but I can't see anything, except my mouse.
EDIT: I'm not the only one to have this problem aswell. It seems that loads of people have got it.
