I've had the game and the DLCs from the Ultimate Edition for ages with no problems, but when I tried to play it today the DLCs aren't loading, this messes up all my saved games as well. I've tried reinstalling them etc. but no joy. Any suggestions on why they've suddenly stopped working and how I can fix this?

Cheers!

Double check that you're signed into the right account, and that you selected the correct memory storage.

Thanks, tried that already - no joy!

Does the system show them as actually installed? Or present in memory?

And, you are playing Online or Offline?

Look in Game Activity and see if the time you spent in the game and DLCs is there.

Check to see if you have any of the DLC achievements
