How do I get an Arcade game thats saved on my xbox 360 hard drive to my gamer account.?

My friend came over and recovered his gamer account. Then he downloaded castle crashers to gamer account. The game is saved on my hard drive but not on my gamer account. Is there any way to put it on my gamer account?|||No, you can't transfer anything between accounts. So even if the game is on your hard drive, you won't be able to play it without his account.
