Native Access 2 wont let me reinstall a plugin

This isn't my first time uninstalling a plugin on my iMac. I do it at least once a year and never have any issues.

Recently, I've moved all my plugins to a different external drive and deleted all files from my computer and all the source files to the best of my knowledge. The Plugin is called "Shake, Shimmer, Strike 2" and Native Access only has the "locate" option and won't let me uninstall or install it.

I tried to choose a location when it says locate. It says invalid path, even when I select the original location (where the files no longer exist) I even deleted the .plist files, I think they're called. I've even re-entered the activation code but it still only has the "locate" option.

I feel like every other plugin was easier to fix by just choosing "uninstall" and then picking a different location to install it to. Any help would be greatly appreciated. I've exhausted all my options with google searches.
