I have a crash in the game and cannot go past a specific point in the game.
The last thing I can do is enter the 2nd spear, then crawl to the VTOL, jump onboard and watch the cutscene.
As soon as the 3D map of the Prism has been shown the game crashes to desktop.
This is reproducible everytime and I have found evidence on the web that other are affected by the very same issue.

OS: Windows 7, 64 bit
RAM: 4GB
CPU: Phenom X4
GPU: RADEON 5770
CHIPSET: AMD 770

Game is installed on an SSD with 10GB free space left.

Windows 7 SP1 is installed, latest GPU driver from AMD has been installed. All chipset drivers are up to date, system is a new install, especially bought to play Crysis 2.

Any advice how I can get past the crash?
