Unfortunately, it did not work, and now i doubt that anyone could fix this, because ive been searching for a long time....

I have installed halo 2 for vista on my windows 7, it works fine, but when i get into the game, the options to play online multiplayer and network LAN are greyed out for some reason. I have inserted the Games For Windows Live key, so i see no reason why it should be greyed out... Has anyone experienced this problem before ? If so, can you please explain how to fix it ?
