The Multiplayer DLCs (Resurgence, Rebellion, Earth, Retaliation) are all free. What you're talking about are the Single Player DLCs like Omega, Leviathan, From Ashes, which are paid DLCs but are not needed for any Multiplayer-feature at all. Look up Retaliation in the PS store if you don't already have it or if you do try to do a repair or re-install. This should enable the challenge system.
I'll check it out again.
Thanks for all the help!
I reinstalled retalliation and now it's there. I can't believe how many challenges I've actually completed and never got credit for! Oh well....more incentive to keep playing!
Thanks again!
Glad to hear it worked - have fun with the challenges! 🙂
