Tips and Tricks for Using Zero G Nostalgia in Kontakt

Does the library show up in the library pane inside Kontakt? If it does, then it has to be auth'ed. If it doesn't show up as a library in Kontakt and requires the full version of Kontakt then you are fine. Some Kontakt instruments do a serial number request as part of the instrument (home brew copy protection). I didn't think East West did that though, but it's certainly possible.
