Harley Quinn and Arkham bundle DLC's that are on my hard drive but do not load into game

This explanation is a little long winded but bare with me please. I originally bought Arkham city GOTY edition and with it downloaded the Harley Quinn, Arkham Bundle, Challange map Pack and the Catwoman Bundle. Money got tight and we sold the game to
gamestop. Just last month we had a little extra so I bought the game agian but this time I bought it as a digital download. Although the Cat Woman bundle is playable and loads, the harley quinn and arkham bundle do not. I am not sure about the challange
pack just because I don't know that is. However I can see The Cat Woman bundle saved to my hard drive as well as the Harley Quinn, Arkham bundle and the challange map pack. So I know they are still on my HD but they for some reason wont load into the game.
Now that answer could be as simple as The disc I bought previously was GOTY and the Download was not and if that is the case, fair enough. I will buy the dlc's later. BUT if there is a way or if they should be loading and just are not for some stupid reason
I would like to know if anyone has any ideas. Also, if I go to the game in the xbox live store, the game shows up as "play now" and when I go to the DLC's they all ask for me to purchase the content which would make sense if they were not on my hardrive
all ready. Even the Catwoman Bundle show up as "buy now" rather than re-download even though it is currently loading when I play the game. I hope this all makes sense and Thanks!

problem with batman arkham city GoD and GOTY

I downloaded the GOTY content on a defunct 250gb hard drive that stopped working. I've been trying to get it to install on other hard drives but it always freezes and refuses to download the Arkham Bundle and Harley Quinn's Revenge.

I have the GOTY edition and I can't get the same two DLC to re-download on my new hard-drive (the old one died, never buy 360 parts on amazon). I'm wondering its an update issue or something. Hoping someone has an answer for us.
