My Cod5 Multiplayer on Xbox Dosnt Work It Just Glitches. How Do I Fix It?

Okay I go on multiplayer on the main menu and it starts to load and just keeps saying loading then it glitches then comes back e.t.c. I then sign out and it says PATCH_UNEXPECTEDEXEPTION.

I tried it on other profiles and it works!! Only on my profile it dosent work! (This is on XBOX)

Suggestion:

try deleting your profile from your hard drive and then recovering it. make sure you dont delete your save data and that you know your password.

Im sorry but thats all i can think of :/
