WHoo-hoo! That worked. I wonder, though, if part of the problem could be that I was trying to install on my regular user account, and not as the Admin? (I don't surf as Admin.) Because after the cleaning, when I went to install my upgraded version, I got a little message saying I didn't have enough rights. Oops! Logging on as Admin, I had no problem. So I'd suggest to Gilad that he try installing as Admin, if he hasn't already.
