How do I re-download maps purchased for cod ghost on the 360 on my series x?

Hi, I'm Luis a Xbox user just like you. Thanks for reaching out us here. You should be able to locate them at the add ons tab.

In My games & apps, highlight a game (but don’t select it).
Press the Menu button  on your controller, and then select Manage game and add-ons.
Select the game tile, and then select each checkbox for which items you want to install.
Select Install, to confirm the installation.

Update:

What I have done is deleted my 360 file on my Xbox Series X and let it re download itself when I opend the game Left 4 Dead up because it wont work in game and will come up with the error, however the series X will download it on it's own when you boot up a 360 game.

The bad news is that my Xbox 360 still comes up with the error when Downloading my profile, so something to do with that way of downloading is the problem it seems.

The Free Fall map for Call of Duty: Ghosts will be sent out to users three weeks after your purchase of the digital game.

You also have to purchase the game before November 18, 2013 to get the map, more info here:

You're positive it's not in your download history? Did you scroll down further? (Dashboard, Settings Tab, Account Management, Download History)

Also, go to your storage (Dashboard, Settings Tab, Storage, Storage Device, Games, CoD: Ghosts) and see if it's there. It may be corrupted, in which case, delete the corrupted file and navigate to the CoD: Ghosts add-ons screen to re-download the map.

Let us know if that helps. =)
