Backwards compatibility wont work?

My xbox one works fine and always has done, anyway i heard about this new backwards compatibility feature so i decided to download dirt 3 which i previously owned on my xbox 360.. my user profile on my xbox one was carried over from my xbox 360, so it eventually
downloaded and i try to play it and it comes up ''the person who bought this needs to sign in'' sign in with the profile used for the purchase or buy a copy from the xbox store.

but i bought the game on my xbox360 and t was with the same profile? so why wont it work ?

HELP

They wont be adding any more games to the list, Microsoft have stopped working on backward compatibility.

 

Hello aaronkehir1

You can sign into your account and check your download history to the profile that you think you bought it in. If not, you can try these trouble shooting steps here and if they do not work, fill out the survey when you are done.
