Actually, I don't use Live and don't plan to... (how is/ and how do i connect to xbconnect? They're free and aren't concerned about modded systems, right?)

Having accidentally activated the LIVE function of some game, the dash attempts to update itself and creates two directories in the C: partition. Off the top of my head, I don't remember what they were titled.

Luckily, I had the contents of the original C: partition stored and just FTP'd it back, overwriting any changes that the LIVE attempted to make. Everything works great again.
