If anyone has similar issues try this workaround tip (shown below), as it restored those libraries of mine back into Kontakt version 5.5.2 after all else failed. I contacted the support from those two library companies and they were aware of the issue and were working with N.I for a fix.

, as a resort I reinstated Kontakt version 5.5.2 but the problem with those same two libraries remained as in version 5.6.5 ? ,Īnd it stopped a couple of my 3rd party libraries from being shown, or loaded etc

I downloaded and installed Kontakt 5.6.5.
