Free Kontakt 7 Player Stops working after 15min with the Free Native Instruments

Hey Native Instrumentarians,

So I ve used Native Access and downloaded some of the free instruments & stuff including Kontakt 7 Player. When I load it in my Daw and use it. After a couple of minutes I get the message that the instrument requires registration. I have only downloaded and use the free libraries like Kontakt factory selection 2 and some others that were available through native access. I thought that kontakt player supposed to work without time limitations. I've repeatetly entered my serials in NI access and i get the message for a successful registration. It stills says demo in NI Access though and still get the message in my daw after 15mins. I attach some photos. Check them out and tell me what I am doing wrong cause it seems that is not easy to contact NI . Support is all automated and no subject seems to fit in my situation. Thank you
