I know a lot of people have asked for help with this topic, and I have followed all of the advice I have found.
I have deleted the Crimson DLC, cleared my cache, deleted the Spartan Ops 1-5 save file, deleted the title update, deleted the Halo 4 save file and re-installed the two discs, and re-downloaded Episode 6-10 mulitple times, both from the in-game menu and the marketplace.
Even after all of this, I can't play Spartan Ops. However, when my brother signed in on my console, it worked fine for him and I can play it on his console.
Does anyone know why I can't play it on my profile on my console? Any help is much appreciated.
Tried it. Didn't work. Thanks anyway, I hadn't even thought of trying it since every other game I've ever owned works perfectly fine. Unless it needed patching, but those developers actually fixed problems with their games.
