With an extended session of rooting through directories looking for remnants, the VST version of Super 8 is no longer on my Updates page asking for a "Repair."
Here's where things get weird. Super 8 (VST version) is still showing up in the Library, despite every attempt to clear it out. But do you what else is showing up in the Library? "Abbey Road 60s Drums" (NOT "Drummer"), "Akoustik Piano," and "Elektrik Piano 1.5".
How do I finally purge these ghosts from the Library?
