Hello there Bountyhunters7,

If you are playing on Xbox, I would go to My Games and Apps and then press start on MCC, go to Manage Game and Add Ons and make sure Halo 2 is popping up there. If it is not, you should see a spot on there to download it. If it is already downloaded, I would uninstall it and then re-download it.

Hope this Helps,
