Unfortunately I went to look for the gamekey and found this: Game Activation Key: No key assigned
Just great. I'm going to email WB and MS and see if they can help. Not looking too good for now.
Yeah I was on the line with xbox support for an hour and twenty minutes and we finally got it working. I ran into the same problem, unfortunately. Bioshock 2 and Viva Pinata had their game activation keys, but not Arkham Asylum. The guy at xbox said to contact steam and see if it was possible to get a key using the LIVE access code, but we all know how quick steam support is...
This is HUGE. I honestly thought this day would never come, I am freaking ecstatic. Except it's a shame that I'll lose my 100% saves and achievements in both games, I even got Campaign Kitty. That was freaking hard, let me tell you. But dammit, it's worth it all. Winning the war on DRM is worth way more than winning two awesome games.
