A while back I bought Tales of Vesperia on my brother's Xbox Live account, as I didn't have one. There wasn't enough space on his HDD, so I bought a new HDD for myself and made an Xbox Live account on it, but as I'd purchased the game on my brother's account we had to use his account to download the game.
Now I have my own Xbox 360 and I've transferred the data from the HDD to my new console, but because it was my brother's account that downloaded the game I don't have the license for it and can't play it. I can't do a license transfer using my brother's account as it appears to transfer all licenses in one go, so it'll transfer them all to my console and he won't be able to play any of his own downloaded games on his console for the next 4 months.
Is there a way to resolve this, or am I simply going to have to spend another £20 to buy it on my own account?
