Why do I keep getting a Fatal Error window when I try to run GTA IV. I have installed correctly and activated it too but it just won't work for crap. I was told to download Windows XP Mode to try and get it to work but i tried it and it still won't work. I'm up for any suggestions and My OS is genuine and everything. If someone could help me then I will greatly appreciate it. The Error Code is like W560 I think. I will find out tonight.
