Help

Hello again, thanks for your help before with the sound driver, my speakers are back up and running. Now i tried to install Wolfenstein Enemy Territory on my Dell Latitude D600. I keep getting the error message “GLW_StartOpenGL() – could not load OpenGL subsystem”. so i talked to my ET buddies and they suggested i update the video drivers for my video card. i do not know exactly what video card i have so i hope that you can help me.
