Hi all. I've got strange proble with my MOH:PA director's edition. Then game starts I simply can't move, only just look around(yet in the intro movie threre's no guns in soldiers arm, they flying in air instead of swimming with boat and etc...)
What the problem it could be? Any help is appreciated. Thanks.

AMD Barton 2500+

Asus Geforce 6800 128Mb
Windows XP + Service Pack 2
