I have EXACT same problem dude here!
I got TonePort UX2, was using Pod Farm 2 for a long time, but since few months, can't get it to work as it says Pod Farm 2 isn't autorized... But In fact I was using it.... I'm also not confused about versions 1 or 2, I was able to use split tone, I created split tones... But now can't do anything... WTF?
