Hi! Iam playing the german release version.

My system is:

- AMD Phenom II X4 955 4x3.20GHz

- Gigabyte GA-MA790XT-UD4P 790X

- G1024P Club3D ATI Radeon HD4890 1024MB video card

- 4096MB Corsair PC3-10666 CL9 Kit (DDR3 1333+)

- 680W SuperFlower Atlas Design Modular

- (temps never higher than 55°Celsius)

- (on Windows Vista 64). CPU/GPU not overclocked, fresh BIOS (may 2009)update.

Sometimes there are errors during the campaign, the game often crashes when they appear. Sometimes I get this error (crash to desktop): http://img20.imageshack.us/img20/6549/aaatuo.jpg
