Thanks, Aaron. LOL, I had just downloaded it yesterday (1.04) so I downloaded the new one to which you refer and it re-installed nicely.
I didn't do an uninstall before installing the new one and CCleaner tells me I have zero registry issues after the install. This leads me to believe it's OK to just install this update over the old one (version 1.04 to 1.05 in my case).
