I recently moved all my sounds, samples, and instruments to anotother external drive and am in the process of re-adding non-player libraries back into Kontakt 7. Most of them load but there are some that when I hit the gear and then "add", the name of the instrument shows up in the folder list but it does not get added to the main library window of Kontakt. I understand that certain instruments are incompatible with Kontakt but why do they appear in the folder list? Shouldn't I get a message saying that it is incompatible or something similar? Am I doing something wrong? Should I jsut assume that if it doesn't show up in the instrument library, I can't add it?
