Help with L4D2 DLC problem

So i havent played on xbox live in about a half a year, i bought the left for dead DLC's way back, as well as the updated left for dead 1 maps to go with it. I had to get a new xbox 360 and now i have set everything up, but when i try to download my DLC's
it wont let me saying they are corrupted / unsupported. It shows i have them but when i try to download it wants me to pay all over again? I did read that since i swapped my HDD over with all my stuff that i should be able to download it to my new 360. anyone
got some ideas on how to fix this?

Left 4 Dead 2 backwards compatibility download DLC

I owned the 360 version of L4D2 and owned all of the Dlc. I now have an Xbox one that uses the same account that i used when I downloaded the game + Dlc on the 360. I had to repurchase l4d2 digitally due to my original disk being scratched. I was wondering
if I could redownload all the Dlc that I had again for free. Any help is appreciated

Hi!

Be sure to use the same account used for purchases made previously. Then delete the

corrupted data (the same procedure to delete the corrupt saves) and try again to download the DLCs.

 

I have done that but it still is trying to make me buy them all over again now. when i got to he download section there is no option to reinstall, only to buy. This is really frustrating and im seriously considering cancelling my subscription for good over
this.
