When you re-download it instead of hitting continue or play now just keep pressing B until you completely leave the download screen and your back to the double dragon main title screen and bravo, you will now be able to play the full version.
I have a new xbox at home because i took my old one to work so i have to re-download any xbla games i have because a lot of my older xbla games are registered to my old xbox at work.
I just tested that method again hence classic megadrive sonic is my most recently played game.
