I was playing for 3 houres and crash to deskop, c++ runtime error, anyone know how to fix it plz?

By the way, i use the high res pack and the game runs very smooth 50-60 fps, so i dont think is a system problem, here my specs.

Amd Phenom x6 1100t 3.3 ghz (3.7 with turbo enabled)
4 gb ram ddr3 Corsair Vengeance 1600 mhz
xfx Radeon HD 6850 1gb ddr5
Windows 7 Home premium 64 bits
