Hi guys I just downloaded LA mod few days ago and I found a really serious problem. After I installed the mod, and when I start it, there isn't any problem. However, after about 5 minutes since I begin any missions or a freeplay, the screen turns black and weird sounds come out. I tried fix this problem by myself, but I couldn't find any solutions. I started it as a administer, I deleted the program and re-install it about 30 times but I couldn't fix it. My computer is a HP Pavilion dv4 laptop with i3 core (2.13GHz), 2GB RAM, and ATI Radeon HD4550 Graphic card. And most importantly, it is Windows 7. When I installed it in my old laptop, which has worse performance and based on Windows XP, there wasn't ANY PROBLEM AT ALL Anybody knows how to fix it?
