So I've been running the game with no problems, with the settings on highest. The game now crashes after the tower explodes on the cut-scene into the new level. it does the "they ambushed us and derailed the train..." and then black screen with nothing going on. I move my mouse around and see the mouse appear just in the middle part of the screen, hinting there's a window there. I Alt+Tab and its a Error message saying Crysis has stopped working and is looking for a solution ( windows7 standard error message). Now I've tried many times and many things,looked on many sites, I crash always on the same spot and no one has a solution to this. It has people with Nvidia and Ati graphics cards and 32 and 64 bit, still no one has seemed to found the fix for this

Has anyone found out a way to fix this?

My specs
Ati radeon HD 5700 ( not very good, I know)
16 gigs of ram G-Skill ddr3 1600
Intel i5 2500 cpu@3.30 ghz
Windows 7 Ultimate 32bit
1.1 terabytes HDD free
