Buying downloadable items
Downloading items that you have already purchased
If you are attempting to play Exo Zombies in Call of Duty: Advanced Warfare, and you receive the message "A downloadable content package was removed or all profiles are signed out", you’ll need to allow the free DLC “Compatibility Pack 1” to be downloaded and installed. To do this, log in to Xbox Live, start the game, and you should see the message “New required content has been added to your Active Downloads. This content is free and required to play online.” Allow the content to download and install. You can check its download status by going to Active Downloads: Xbox button, Games & Apps, Active Downloads.
