Return To Castle Wolfenstein can't load OpenGL Subsystem

I've just re-formatted my hard drive, installed XP for the second time, downloaded the driver for my NVIDIA GeForce4 MX 440 card from microsoft.
Unlike before, when everything worked great, I get the following dialogue when I start up Wolfenstein:

GLW_StartOpenGL() - could not load OpenGL subsystem

GLW_StartOpenGL() - could not load OpenGL subsystem

I just downloaded the new driver from NVIDIA:
    41.09_win2kxp.exe. Windows told me not to install it as it is unsigned.

My system: Asus A7V333 motherboard
           Athlon xp2100 cpu
           1/2 gig ram
           80 GB hard drive
           Windows xp with sp-1

thanks
