Plugin slows file manager

Mtpdk2 drumkit has been acting alright for a few years.Then all of the sudden it takes minutes instead of seconds to load up. It had to be taken out of the blacklist and reactivated. Is there any fix for this? I have tried all of the suggested ways to fix it from other forums. I’ve had this simple plugin for a long time and would like to keep it.
But maybe you could talk me into it if you could point me to simple rock beats in the cubase sound browsers.
