Short of fire or running over by large vehicles, not too much is irreversible- at least with software changes!

I also had run the uninstaller, so we're both in the same boat. I'm going to try the installer on another thumb drive I have and see what happens. I'll let you know.

I KNOW this must be possible. I like that info about the Removable Media bit (0/1)... that may be a line to persue. If I can get the USB to answer the query with just that one bit changed, all of our troubles will magically melt away!
