All of the download codes work fine! It seems to be impossible to locate the unlockable "on-disc" content though! The soundtrack, backgrounds, and weapon camo...where the hell do you find them?
If you check the booklet with all the codes it tells you to go to www.callofduty.com/blackops2ce, log in with your profile details and enter the code that is on the back of the quadrator side of the coin, at the top, hope this helps
