I purchased the Kontakt 2 Crossgrade. It won't install without the serial number for my previous installed product, Kontakt Player. However, Kontakt Player does not allow me to register. I assume that I need to go through Finale->MIDI->Native Instuments VST Setup->Finale GPO->About Finale GPO and use the Registration tab. However, I see no button or link on the tab page to register. Is there another way to register the Finale GPO version of Kontakt Player?
