Halo Channel: Halo Nightfall: BUY HALO?

I have loaded my disk copy of Halo TMMC. And I am trying to watch Halo: Nightfall Season 1 Ep.'s 1 & 2 and it keeps telling me to Buy Halo!? Why!? And how do I fix it? Please help.

I found how to fix the issue I needed to enter the 25 digit code that was included in the disk copy of Halo: TMCC!
