I have to reinstall my cod multiplayer...

yeah,my computer hasn't been working with call of duty for a couple hours.I keep on trying different things to try to get on,but nothing.I then realized that I didn't fully install multiplayer.I never used it before,and I didn't think I'd start now.so yeah I'm going to have to reinstall and try again,hoping for better results.
it seems like my computer hates me.

did you try deleting the server cache ?

go into your cod folder and delete a file called "servercache" it's a pain in the behind...
