Strange, if you want to do further testing, to see if it's a common issue, I can try installing on a "FRESH" new drive, on a different machine from a different IP address. Your first post, you re-installed and then went to autoupdate.. <My game machine is pretty much empty.. Just a few games, and some auto-configuration stuff that I have turned off; never been online, never auto-updated windows, I could try doing an auto-update on it to see what happens, see what part of the drive changes compared to my backup image.
