Please help me! I have been trying to play ME for a while now, bought it through steam a while back and got the game to boot up. I could create my character and then the game would crash. After about 5 times I tried unistalling and reinstalling and now the game won't work. So I unistalled and got a friends disc copy of the game. I have a serial already purchased and everything. When I trying to install the disc I am getting a white screen! Why does this game hate my system so much!

I have an Intel i7 920, Radeon 5870, 6gb of ram, etc. I should have no problems!
