Dear Barsoom3
The site was up only for internal demo and testing, but obviously you were on the right place in the right time

Version 3 is about to be released but it is not out yet. The copy you have is OK, you can use it if you want. To use it with folders protected under Espionage V2, you simply restore the folder within Espionage2 back to normal, and then add them to Espionage3, there is not direct migration path because the technology used is quite different.
I hope this helps.
And good luck in searching the invisible on the net
