Understand that there's a reason NI licences libraries to be used with Kontakt Player. It is revenue for them. All KP licenced libraries will NOT time out. But, not all developers can afford themselves to licence. For those libraries it is clearly stated that you can load them in Kontakt Player, but in demo mode, and for regular usage a full version of Kontakt is recommended. Besides, IMHO, Kontakt is a staple of modern audio production. Anybody half-serious about their work should have a full version of it.
