I've got a standard PC with Windows XP, I followed the instructions to allow my PC to access my Xbox 360 and visa versa: http://www.xbox.com/en-US/pcsetup/alldownloads.htm My computer already has "Windows XP Service Pack 2" and "Windows XP Media Center Edition 2005" (although I don't remember downloading it), and asks to download Rollup 2. However when I try to download, nothing happens!? I have my Anti virus prog switched off, tried connecting the pc to the xbox, let it go wirelessly etc., and still no luck... Anyone had the same probs?
