Error playing any Quake 3 game (RTCW, Jedi Knight 2, etc)

This is the error i recieve in the initialization console. I wonder if anyone else gets this.

Initializing OpenGL driver
…getting DC: succeeded
…GLW_ChoosePFD( 16, 16, 0 )
…39 PFDs found
…hardware acceleration found
…PIXELFORMAT 3 selected
…creating GL context: failed
…failed hard
…restoring display settings
…WARNING: could not set the given mode (6)

…calling CDS: ok
…created window@0,0 (1024x768)
Initializing OpenGL driver

RE_Shutdown( 1 )

…wglMakeCurrent( NULL, NULL ): failed
…releasing DC: failed
…destroying window
…resetting display

Than the message flashes:
Q_strncpyz: NULL src

Anyone knows how to fix this error? I have Geforce 256 and use Windows 2000.
