X Error of failed request: BadWindow (invalid Window parameter)

Minor opcode of failed request: 4 ()
Resource id in failed request: 0x360000f

I use single kde4 desktop on two monitors.
System: Linux 2.6.32-5-686 Debian Squeeze 32-bit, nVidia GeForce Go 7600.

Is there a way to fix this/play the game?

EDIT: Never mind. NVidia driver wasn't properly installed.
