NSK Demo uninstalled: "No valid license found for NSK..." ??

Hi Breeze,

Please check if the presets have be de-installed:

C:\Users\YOURUSERNAME\AppData\Roaming\Steinberg\Content\VST Sound\ADD_SMT_120_Neo_Soul_Keys_Presets

If this file still exists, just delete it to avoid the popup.

Does it work?
