I just bought Call of Duty: Ghosts and tried to play multiplayer online. Going through the menu, I selected 'Multiplayer' then 'Xbox Live.' After selecting 'Xbox Live,' a notice pops up stating "The current profile is not allowed to play on Xbox Live." I know my membership is still active, and I am able to play other versions of Call of Duty online. Why is there an issue with the Ghost version, and how can we go about resolving it?
