Well, NI support forums PROBABLY gonna be more help. I'm thinking perhaps it's looking for Native Access in a certain directory and maybe I moved it? But it never worked to begin with so I dunno what the issue is. And the files I'm trying to add are from Impact Soundworks, and are compatible with Kontakt. I've tried a few things to make it work, but I just can't figure it out. Kontakt's Factory package thing and Super Audio Cart works just fine and I added them with Native Access. So, I know how it all works and stuff but when I go to Kontakt 5 in my DAW and hit the 'Add Library' button to add files to it, a prompt tells me I need to download Native Access, which would be great if I didn't already have Native Access.
