XP Pro and Return to Castle Wolfenstein

I recently upgraded to my machine to XP Pro, and now every time I try to load the game I get an error message saying “cannot open the OpenGl subsystem.” Can anyone help me.

SEE RE:OPENGL ON THIS SITE

I am having the same problem with the

OpenGl thingy What do i do?

Holy crap!

Just get the XP compatible drivers for your 3d card since the ones that are installed by XP dont support OpenGL.

Is it REALLY that hard?
