Wow, just did the same as all you guys BEFORE reading this thread - now my maps are completely gone :(. This totally bites. Yet another example of Microsoft's lunatic bureaucracy - they should have the content available until shutdown, even as a goodwill gesture - totally kicking us in the face for not doing so. I have seen a few tutorials about getting the actual (completely legit) map files from an external server, then bunging them (and a file structure) on the 360 HDD with a hard drive transfer cable. Could this be a workaround, or will the same 'corrupted maps' problem surface again? I just want to confirm before shelling out on a cable.
