OpenGL does not run. Please help!

OpenGL does not work ... when I launch a game (any) with OpenGL (Demise in this case) I get an error: "GraphOGL: Can't create context. Pixel format is not valid" The last sentence is in italian, the first in English.

I'm runnning Win2K (sigh) on a K7V, AGP4 Geforce 256, SB Live 1024 w 256Mb RAM.

Anyone knows if there's a fix or how to configure OPenGL?

Thanks

Read the topic "finally my opengl works"

...I'm under W2K! There's no WIN.INI!

None has any clue. When do you get such a message?

Thanks
