Hi, lorn.
I installed the app to see if I could give you a hand. After I unpacked it, I started to look through it, and things seemed broken. I assumed I unpacked it wrong, so I tried using the original packed binary, and I still couldn't get the app to work. It seems the app is either really buggy, or just doesn't like my computer.
Either way, sorry I can't be of any real help here.

I uncovered some stuff looking through IDA's disassembly of the app (the 'Enter License Key' form's validation code, and the code that then loads the key from the registry on app startup, and the code that shows the license/trial info on the about screen), but I assume you have already seen all that.
Regards
