Howdy,
Another "quick and dirty" experiment is to just download the GPO Studio (available at
http://www.garritan.com/downloads.html ) and see if it will allow you to use it for Kontakt 2. It may not work, but it might be something to try in the interim while waiting for a response from NI.
Or, you can try the NI downloads page. It seems to change every time I've gone looking for it, so I don't have a url for that one.
ttfn,
Sherry
