So I'll make this really simple.
I bought CoD hard edition and activated the season pass, inserted the disc and found nothing no DLC maps and no other bonuses.
I checked my account and it says that i already downloaded it whats wrong
If you can download this then it's working - Call of Duty®: Ghosts - Season Pass Pack | Sony Entertainment Network
Nothing else to download at the moment, you'll have to wait a few months until DLC starts getting released.
