Create a project with last version, remove the serial and run it on a device. Bottom of the error on device, it says: 2009 Sencha Inc.
Adobe aquired makers of Phonegap, Look at competitor Titanium Appcelerator's investors. Sencha got lots of fundings from investors, it might be possible they have interest on NK for native apps.
If I were creator of NK, I would sell it for a few millions, got company share options and be employed as NK Coordinator with good salary. It would be more profitable than selling licences for $100.
