Hello, I know this does not relate to matchmaking, however I i had no alternative place to put it. I am having trouble watching Halo: Nightfall. I have the Master Chief Collection, but when i try to watch an episode it gives me an option that says "Buy Halo" instead of play like it did before. When I hit "Buy Halo" it starts the game. I have tried many things to fix it, such as restarting my Xbox, Reinserting the disc, ect. If anyone has a solution or can get this through to 343i (As i am having immense trouble e-mailing them and I don't like social media under any circumstance). Thank you.
