Up until two days ago Half-Life, Quake2 and Q3A all run fine. Q2 still runs fine but when I start HL or Q3A I get this error:

OpenGL Error
X Not a Wicked3D Voodoo2 board (glide2x.dll). Board with multitexturing is required. Use the other version of the driver for boards with one texture unit.

400MHZ Celery
Voodoo 3 3000

Any help?
