That conversion utility never worked for me - I couldn't get the program to launch on my computer.

But no matter - I worked out how to transfer presets to either unit and it's a very easy fix  

The desktop POD HD saves a setlist file with the extenstion .hbs, POD HD Pro saves the same file as .hrs.  To open the file from the other unit you simple have to change the middle character to suit.  For example if the file was named presets.hbs, it would become presets.hrs.  Easy peasy, and works like a charm.
