so the other day i tried to play streets of rage 2, but it said i had to unlock the full game. i bought this game awhile ago but it was on my old 20 gigger. i heard something that brad mentioned on the latest podcast about him having to transfer some kind of data to play street fighter hd or some shit. what do i have to do here?

nvm i found out http://www.xbox.com/en-US/support/systemuse/xbox360/licensemigration/

Are you playing on the same account you bought it on and are you signed in?

I have the same problem with Sonic 1 and Golden Axe (but not with sonic 2). I did the license migration, called them up, they told me to clear the cache, delete the games, re-download trough the download history and all that stuff. Nothing worked.
