The problem is that when i'm loading up any instrument it only shows blackscreen like in the image.

Long story short, I recently download Tokyo Scoring Strings from Alldebrid using Jdownloader2, it was messy as hell after downloading since it not following the folder structure. So, i'm trying to clean it up by referencing the strucute folder from that russian tracker site. And when i'm trying to load the instrument, it's still fine, no problem. Then, because the file is too big for me, i'm delete the back.nkc and side.nkc mic file. This is where the problem start happening.

note that i'm kinda forget when problem start happening. It can be happening after i'm cleaning up the folders or when i'm delete those two file
