oldsod and zasuituser
The malfunctioning MoreInfo button finally got to me, and I tried the only thing I hadn't tried IMHO!
I downloaded the latest version of ZAPro and uninstalled the 5x version (clean uninstall with rmlicense, just to make sure.
Then I installed the new version, and voila!
Suddenly the MoreInfo button works.
No more Error Page!
I have to conclude that the new license key will only work with a version that has the added features that the old ZAPro didn't have.
The firewall worked, but the Smart Defense Advisor did not.

I turned off the added features, and the 7x version is almost as fast as the older one, but it sure is a larger download.
I've got lots of free space on the hard drive, so that's not a problem.

End of a long thread.
Thanks so much for all your help.
