I didn't make it!
everytime i try to start the game ( both single and multiplayer ) the screen turns black for a few seconds then brings me back to the desktop and in the little box it says: GLW_StartOpenGL() - could not load OpenGL subsystem id really appreciate someones help on this.
That means that you need to load the OpenGL drivers for your video card. Most other games will use DirectX. You need to load the OpenGl stuff and then you will be able to play. I would go to the website of your video card manufacturer and find the proper drivers.
