I am owner of the current Komplete Collector Edition. I also have always had an additional Kontakt-Licens which I recently updated to Kontakt 7. I have recently bought a third PC for my Setup. It is a Server-PC with Dual-Xeon-CPU and 256GB RAM to come along with a large Amount of Orchestral Samplelibraries.
As far as I am informed, a third PC in the Setup cant be a Problem when working with the Collector-Edition especially when another additional Kontakt Licens was recently updated to Kontakt 7.
But since Month I have a severe issue with instability of the Kontakt Licening-System. The first Support-Request Answers and researches led me to the workaround to delete or replace the current Native Access.xml in the Folder "C:\Program Files\Common Files\Native Instruments\Service Center". That has helped for some times. But finally does not solved the Problem at all. I already have a directlink to that folder on my Screen and do delete more and more often without satisfying result the Native access File (including restart of the System and restart of Native Access). In so far I do have the impression, that there must be a bug which prevents me to make use of my license of Kontakt 7 and the Libraries I have licensed for it.
It is a pitty, that Native Instruments has closed their personal Support-Section, which I have expirienced in many years to be very efficient, serious and helpfull. The current Bot system just do not understand anything at all about the Problem I have and I would be very lucky, if anyone in the comunity would have the time to read the full post, think about the possible Reason of the Problem and is able to make constructive suggestions for a solution, but however, I still believe a professional personal support would be the right adress for problems like that and I hope Native Instruments would keep up the quality of Suport I am used to get previously.
kind regards
