I recently bought Alice: Madness Returns and it came with a redeemable code. I redeemed it and it gave me American McGee's Alice. I played through the entire story mode of Madness Returns with no problems at all.
Since that's done, I would like to play the downloaded content. But I can't. Every time I try to play it, I get the loading screen for the game and then it pops up that the disc is unreadable.
I've also had this problem with the Resident Evil 5 Gold Edition and it's downloadable content it came with. I could never get that to work either.
