I have the same problem.
I have the FX Junkie model pack from when I ran it on my old (now stolen) macbook.
Tried loading the original CD of Podfarm etc. but the driver won't work Yosemite. No probs, I downloaded everything from the site, but now even though I see the pack is recognised with my UX2 connected, it will only load up with the Trial pack!
Can anyone help me please?!
