[COD2]Multiplayer Help

Right, i have COD2 for the pc and ive installed it. Single player works but when i load up multiplayer it shows the splashscreen and then goes black and returns me to the desktop. Can anyone help me? I have a intel 945GM Video Card and a intel core duo processor @1.86GHz. Thanks

I had the same problem, wait a few minutes and put your screen resolution in COD2 MP to the resolution of your desktop. Hope you understand me, don't speak english well

This can be caused by teamviewer, someone else had it too when I was helping him on Teamview. Make sure teamviewer isn't open.. if it isn't, then I don't know what the problem is.
