Halo 4 campaign levels lost as well as my progress

Yesterday 11/25/2013 I launched my Halo 4 game,and there was an update,so I ran it. After it had finished,and I launch halo4 again. I noticed I am missing all of my campaign levels except for 3 of them, but everything else is still there. I noticed that the game is showing as if I had not started those three missions. I can also go online to halo waypoint and everything is there as well. Could use some help as to why this happened and how I can fix this without deleting all of my stats.

Thank you ,
