Game worked last night - played offline - connected to xbox live and did an update this morning. Can no longer play the Halo 4 Campaign as it says that not all players have the dlc - disc is not scratched - console is working fine - 343 I want to play the game I paid for… Please advise - I have removed all content of halo 4 from my xbox and reinstalled it to no avail a friends disk that works on his machine produces the same result.
