Wii Multiplayer Not Loading Blank Screen

I have black ops on the wii. And when i click on multiplayer, it goes to the loading screen which is a black screen with the word loading on the corner. After a couple of seconds, the screen is just blank and black, with nothing going on. And i have let it sit like that for like 5 minutes and nothing happens. Any one have this problem before or a solution? I think this happened after i updated the patch, but i am not sure. Please help! THANKS!!!
