Hey everyone I pre ordered New Vegas and got the code for the Classic pack. ( PS3 ) But when I download it nothing comes up in my game????

I dowloaded it before I had a save game and nothing happened. So I deleted my save game started a new game, saved it and then downloaded the classic pack agian... and still nothing...

what am I doing wrong or is there something glitching out?

note: I didnt get the error message saying I couldnt download the content.

After I downloaded mine (tribal pack) I had to install it. Afterwards it showed up in the game.
