Thanks for the advice Sol, I've tried deleting the DLC and reinstalling it, didn't work. So I deleted the game data and reinstalling that now. But, PSN appears down and the installation is stuck at 0 lol.
Googled the problem and someone said the issue with with the old "fat" ps3 only, which is what I have. Ah well, more wait ftw. --- PSN: Saiyajin12 RE5: Duo SS ranks 80
