DLC isn't loading and I can't load saves

[k44oqba4p]

I used to be able to resume my last save but that option didn't appear, I haven't played in a few days. Now trying to load a save all of the dlc shows up in red in the additional content and the load button does nothing when clicked. If I open the additional content > mods the list is empty. I can create new games and saves but they don't have DLC. Any help would be appreciated.
