My xbox live works fine on COD ghosts until I try to add a guest. Then it says, "there was a problem adding a guest but it will probably work if you try it again." No matter how many times I try it doesn't work. Same thing happens with other games. Any ideas?
Mayby the game dosen't support guest. or it a glitch on the system. Try the game tech support if it supports guest on the game. And if those said game do. Then called phone support for fixing this. Phone support in US and CANADA is 1-800-4MY-XBOX
