Hi Lance,
You should have received a registration code via email when you ordered? (Or via the store you purchased from, depending on where you got it).
If not you can look it up here:
http://www.versatilemonkey.com/switchThe desktop app is basically just a network transport like Wifi or the cell network, accept it works through your computer. Everything still works through PodTrapper, but PodTrapper is able to use the USB cable to get to the internet. If everything goes to plan you should never know it's there.
You can always download the latest production version here:
http://ota.versatilemonkey.comYou can get the latest beta here:
http://ota.versatilemonkey.com/beta/These can be installed directly over the old one, just make sure you exit the old one first (via Menu->exit).
If you're running in to any issues definitely let me know.
