Michael, I actually meant update rather than upgrade, it may work then for the 15 minutes. I’m not sure why it loaded only once as I have never had the Kontakt Player (I got by on the old 30 minute demo version of Kontakt before buying Komplete and a later upgrade).
You could try changing the name of the nki; add an s to Guitar and see if that lets it load.
If it is up to date, then Decent Sampler may suffice but it hasn’t got the ooomph of the Kontakt version.
