Did you delete any user profiles off your PS3 recently? Are you sure you're looking at the account that you used to buy that DLC?
First I would do a double check at your list. If it's extremely long (like mine), you might easily miss something. If that doesn't work, then try to think if you're SURE that you haven't deleted a PSN or PS3 account. Deleting a PS3 account shouldn't do anything that I know of, as it's not directly tied to your PSN (obviously, that would just be stupid). Are you sure you don't have a second PSN account?
Also, awhile ago I had to redownload WipEout (some file was missing apparently) and I couldn't find it in my download list, so I just went to WipEout in the actual store and I could still download it from there. Try looking at the LBP2 DLC and see if any of them have a red bag at the corner, which means you have purchased them, and you can redownload it to your PS3.
If that doesn't work, try to look up your problem on the internet. And finally, if that doesn't work, I would contact Sony and see if they have anything to help you with. If they don't....well...you're out DLC.
