"Kontakt has encountered a major problem and has been terminated" message.

Kontakt 7 is not working for me after installing some demo libraries from Arturia Minifuse 2. The next day, I get this message and libraries are missing from native instruments. Kontakt states a crashlog file has been created. I've already updated Reaper (DAW) and NI to the newest versions. Today, I'm running into all of these issues and I don't know how to get things back to normal.
