Need help with malfunctioning library.

My kontakt/komplete library vst version seem to not be able to play more than half of my instruments preset.

The bug only appear on certain snapshots files randomly with no apparent reason or pattern to deduct why. I am now at my 5th time reinstalling everything from the pack individually to whole daw to reset everything but still the same problem.

Exemple : the two first lead presets from the "40's key pack". The first work the second doesn't same pack same size same path of installation same folder litteraly just one above the other in the folders somehow one is readable without any bug as a vst the other is not.

Now we could think that the files is corrupt even if i did delete reinstall 5times over . But that where it get even more confusing; Im able to load and play every preset in my stand alone apps. Wich lead me to think that the files are readable since they are working in the standalone version without problems.

Description of the bugg: When triggering the midi of a newly loaded buggy preset for the first time you always ear the same glitchy high pitch staccato sound, always the same pitch no matte what midi key is played but depending the preset seem to have some of the processing (reverb delay saturation etc). After that first trigger and the sound played any other midi input wont be triggering any sound. Complete silence even tho i see the midi being trigger in my daw and on the komplete display but still producing no noise.

I spent way to much on my keyboard instrument and time on this i need help thanks you in advance.
