do i hav to this everytime i sign in and want to play maps
unfortunately, yes.

For people having disconnect problems: This is a problem I have too. I think it's because your not doing it quick enough.

Here is what I do:
Sign into Main profile
Boot up black ops
Go to zombie ...

Arguments: Invalid

Thanks man! Was going pretty crazy without my Zombies
That's the only reason why I don't pay for the map pack. I only play zombies.
