Hi everyone. This is my first post.
Im form Bangladesh sorry if there is any grammar mistake.

In EWQL "Colossus library" ive used a custom ".nicnt" file. it was working perfectly in my Kontakt 5.3.0 few days ago but for the last few days every time i try to load a instrument it says

"this patch could not be loaded
please make sure that the original library activated!"

but when i remove the ".nicnt" from that Colossus Library ,the instruments work but whole library disappears as i restart Kontakt 5.

Note: I've Tried using "quick" option in kontakt 5 but even after removing ".nicnt" file from folder that message pops out again.
ive tried everything like "Deleting registry,re-installing kontakt" but doesn't work.

please help me. im having the most hard time in Music career.

 

I've updated to Kontakt 5.3.1 the problem still exists.

 

I just upgraded from 5.2 to 5.4.1 and my Colossus still works. I skipped 5.3 though. I don't know if this helps. Did you try to install via registry edits?
