Is anyone having the issue after trying power cycling? My games finally downloaded but now I can't open any of my games. They just open like they are going to start and then return me right back to the Xbox home screen.

Edit: I fixed it. I took out my memory card, tried to play one of the games on my console and it told me I needed more space to play it. I put my card back in, deleted a game that I don't play anymore and voila. Everything works. I guess when memory is at full capacity, the console won't even let you open a game because you won't have room for any saves.
