Whew!!! Finally got it working again. I will take one thing back though. Symantec's customer support was very nice and pretty quick but navigating your way through Symantec websites is absolutely insane. Once I finally got my license key (I had to go to licensing.symantec.com which I could never have figured out if I hadn't been forced to CALL them .... on the phone! I don't do phones any more! :)
Anyway, I had to uninstall the evaluation version I'd downloaded and FINALLY, after MUCH trial and error, I figured out that I had to enter "Authorized User" as the name instead of my actual name and "Authorized Comany" instead of "n/a" which is what I originally needed to do to sign up. I also had to download a version one level lower than I had originally (though it doesn't appear to be any difference).
Well, anyway. After 6 hours (it would have been FAR less painful to just pay for the upgrade), I FINALLY got it working.
Dan.
