Can't run ArmA after patching it to 1.01

[sugar_wolf 0]

Hi, I've got a wird problem with ArmA. After I patched czech version of the game to 1.01 when I try to run it I've got a message:

"Error compiling pixel shader PSNormalMap ThroughLowEnd"

Anyone can help?

My rig is:

AMD 2300 MHz

1,5 MB RAM

gf 6800GT 128MB (93.71)

.

Looks like the problem has been solved. It was caused by replacing original bin with one of the modified language files.

So back with Czech language again
