Multiman

So I just recently upgraded my HDD on my CFW PS3. I transferred/backed up all my games to the HDD rather than my 64GB USB. I selected Internal + BD mirror in multiman and when I go to start the game it just brings me back to the XMB. I tried re-installing multiman several times now and that hasn't changed a thing.

EDIT: This is only a problem with Black Ops II, no other games.
