Halo 4 co-op campaign not working

I am not able to play the halo campaign with my friend (not via splitscreen but each on our own xbox and our own accounts) and we can join eachother in the campaign loading screen but we cannot start a mission because the game says I miss certain content which is not the case, everything is installed correctly,

Please find a helpful solution for this party-pooping problem.

Thanks.
