I have old timers disease.  This has happened before.  What on earth am I doing to suddenly make all the instances of Kontakt 5 mute?  play and all the other synths work fine!  This is in splat.  It's just kontakt that does it and it drives me crazy!!!

I have to check this out also. Yesterday, after the update, I tried to use a Kontakt instrument in a project, but could not hear any sound although the midi was getting through fine.
 
I switched to Omnisphere to see if it was a general VST problem but that worked fine and I never got back to try out Kontakt. I will check it out today when I have time.
 

ludwick, mines still all locked and muted, just the kontakt instances..  I wonder whether I should somehow create new  tracks...what a hassle.

Stupid me, I figured it out. :D:D
