I have a idea but I'm not sure if this would work but why not, let's give it a shot.
Go to: Documents\my games and just delete or move the (men of war - assault squad) folder and start the game again. an see if that would work.
if that doesn't work i would guess that your DirectX or 3D card driver would need to be updated or the set up of your operating system may have to be change in the 3D driver setting option for the game to work.
anyway is a shot in the dark, maybe someone else know the solution if my idea don't work at all.
