Me Too !!! Just upgraded on Thursday and created 3 songs. Recorded Primary vocals on Saturday and then hit the buttom to create the harmonies and :-( there was no joy!
Rebooted and tried on some of my older songs without success. It just doesn't work - gives the error message about cant read the chords...I am very bummed.

HP Laptop with windows 7

I have left a message for Tech support - will they actually help me or am I just out of luck? I do really love this product and the new pedal steel solos are wonderful. I WANT TO FINISH MY SONGS!!!
