Campaign playlists not working?

None of the campaign playlists are launching for me,
at first I was not connected to my wireless and I just installed the game and started playing the halo 4 Laso playlist offline with no issues.
I then decided I wanted to play some multiplayer later so I connected to my wireless and started downloading the update.
as it was downloading I went back in to continue my LASO playlist and it comes up with a system message saying “syncing data for halo:…” I tried to go back to my LASO playlist but it did not have the continue option, it registers that I completed the first four missions SLASO but i cant continue from there, at this stage im frustrated and decide F* it ill start halo ce LASO and low and behold it does the start countdown then just chills for a sec then back to the MCC menu.

TLDR? started H4 LASO offline, went online bout halfway through. save for LASO is kill (progress still registered though) and now I can’t even start a new playlist.

would really appreciate a fix for this.
