I recently got a Sonokinetic library, and when I bring it into Kontakt it will only show up with the red DEMO text next to the instrument name.
Please try quitting Native Access, then deleting the "Native Access.xml" found here: C:\Program Files\Common Files\Native Instruments\Service Center Then start Native Access once more. Additionally, please make sure to run NA as Admin: How to Run a Program as an Administrator
If that didn't help, please reach out to support: https://bit.ly/NI_support_NA
