Hey MerHTX16,
Thanks for the question. If I understand correctly, you want to download a past purchase. I would recommend that you read this article, it may be able to help the issue.
Download past purchases from iTunes in the Cloud - Apple Support
On a Mac or PC
- Open iTunes.
- Click More (three dots) in the upper-left corner.
- Click Movies or TV Shows from the pop-up menu.
- Click iTunes Store.
- If prompted, sign in with your Apple ID and password.
- Under Movie Quick Links or TV Show Quick Links on the right side of the iTunes Store, click Purchased.
- Select Not in My Library to view purchased content that isn't on your computer.
- Scroll to find the item that you want to download.
- Click the Download icon in the upper-right corner of the item you want to download. Your app downloads to your library.
If an item is already in your library, the Download icon won't appear.
Thanks for using Apple Support Communities.
Have a good one,
Mario
