Medal of Honor AA - white strip and opengl


I’ve got problem with MOHAA. When I installed it I recieved “could not load OpenGL subsystem”. So I downloaded the newest drivers from Nvidia and game launched, but…
I don’t know why I’ve got white blinking strip on the bottom of the screen.
I’m guessing that it’s somehow connected with OpenGL. Does anyone knows how to slove this problem?

Please help!!
