I installed some digieffects demo plugins but couldn't get them to work correctly. I wanted to remove them so I deleted the file from the FXPlug folder. However, when I start FCPX they still show in the effects browser. If I try to select them they don't do anything. Does FCPX somehow cache the plugins someplace else? Do I need to have FCPX re-scan the plugin folder? Any thoughts on this?
