The libraries I'm having issues are (so far) Albion III Iceni (I have both albion I and II and they work just fine) and Cinsamples Cinebrass Core and Cinebrass Pro. It seems that one thing that also raises this issue is changing the snpid code that comes in a factory nicnt file. I have tried everything - deleted the registry keys, the xml file, verified unique spind number and no results. Please go to kontakt's libraries tab and press the add library button' 'your new library needs to be added before this instrument can be used They show up fine, but when I try to load an instrument I get: Some libries are showing an error msg after I add them to the libraries browser.
