First off, I wanted to say thanks for making such a great tower defense. And although a story is not typical of a tower defense game, you guys included one anyways. And I enjoyed it.

I've read some of the other messages here, but they all seem related to purchasing the You Monster DLC. I have purchased 4 of the map packs, but not You Monster. In fact, I haven't played the game for 8 months or so. So I haven't installed the latest title update either. When I go to launch the game while connected to Xbox Live, it stops at the "you need to download this title update" thing. However, the message only displays for maybe 8 seconds before I am dumped back to the dashboard. So I unplugged my console from the network and tried it again. The game tries to start, but gives an Xbox error "Game data files are corrupt. Please reinstall."

I thought this odd. Perhaps this info will help with the troubleshooting that is going on.

I deleted the primary game file and am re-downloading that now. I will let you know if that helps.
