Many people are experiencing the error message “A downloadable content package has been removed or all profiles have been signed out”.
STEP 1: Just sign into an account with no gold and not registered to xbox live
STEP 2: Load up exo zombies
STEP 3: Press xbox live and when it says need xbox live switch to your actual account
This has proven to work for a lot of users.
