Downloaded Xbox originals wont play on my Xbox 360.

I think you are right disolitude. I rented a xbox1 game that is compatible with 360 to see if it would work. But I got the same message for the disc game, "cannot play, download again."

So it must be something wrong with xbox1 emulator inside the secure sector of the xbox HD. I wish there was a way to completely format the HD and reinstall every thing. Oh well AU$30 lesson.
