Download history content missing

Any items you purchased on your account will be listed in the Download History (Settings>Accounts>Download History). If you cannot see it there then head to commerce.microsoft.com to see if the purchases still exist in your purchase history.

If the items are not listed in either place then you'll need to check other gamertags as you more than likely downloaded them from there.

If they are listed but you cannot access them then you'll need to contact phone support for more assistance.

I would suggest deleting the content off of your device and re-downloading the content it says is missing either through the marketplace or your download history.

You're content may be missing from the hdd but it is not gone. You will be able to redownload all the content you previously purchased from the download history. You can access this on your console by going to System>Accounts>Download History.

This happened to me on fable 3 I took my hard-drive out and put it back in and then it didn't work so I reset my game and amazingly the DLC worked so what you can try is moving your current game file on a USB then on your hard-drive make a new game and then
see if it works if not then just plug your USB in and move the files to your hard-drive worked for me hope it works for you Also if it doesn't work I would contact xbox support they will then get an xbox live specialist to look into the problem and hopefully
fix it

Yeah it's telling me to pay for it again, which i am not able to do, and frankly, refuse to.
