The number of libraries needing updates increased from around the 4 or so I had before to 25 after the update. I know for a fact that I've already updated these libraries and I am loathe to do it again just to make Kontakt feel better.
BTW, somewhat related:
Does anyone have the experience of updating libraries to an external drive on one computer and then plugging the same drive with updated libraries into another computer and being told by Native Access that the same libraries still need to be updated? Drives me mad. Yesterday, I didn't have space on the external for an update (East Asia), moved to the desktop and updated, and recognized as such. Then moved it back to the external, loaded up NA2 and sure enough the library needs an update. WHY!?
