Quake 3 kan ikke loade

Hjææælp!!
Jeg har lige købt et Riva TNT 2 grafikkort og je ghar installeret QuAKE 3
på maskinen, men når jeg starter quake op kommer den med følgende fejl:
GLW_StartOpenGL() - could not load OpenGl subsystem

Please hjælp mig med at få det til at virke. Jeg skal bare spille Quake 3 over LAN i dag.

Her er hvad consolen skriver:
