User blog:Stezza au/DLC for ME3 not showing up

Hi! So I downloaded some DLC last month for mass effect 3 on PS3. It never showed up so I figured I downloaded it too late into the game. Now I'm playing it again and I've just completeled the Geth Dreadnought mission and I still haven't received any messages. I've downloaded and installed them 3 times now, but when I head into the Downloaded Content menu there is nothing listed there. Anyone else have this problem and know how to fix it?? Thanks!
