Thanks Egg, at least I now have something in the way of help. I have been putting off getting the newest release since I have read about people not knowing whether or not to install over the previous release or to uninstall that first. I didn't want to do it without the correct instructions. I was hoping I could wait it out until the CD arrived, but I need to have it work properly now.
I will wait a little while more and see if anyone reassures me as to how to upgrade, safely, and then take my big step.
