Ok, I just killed my CopperPlug completely...
I added Korg Wavestation to Slot 1 of the Player. Since the plug-in is running in trial mode, the Licenser window opened and I clicked on its Exit button to close it. IIRC I then clicked on the name field of the slot where the plug-in was loaded and CopperPlug crashed.
And it now crashes each time I start it, probably because it remembers the last loaded plug-in(s) and has an issue with Korg's Licenser window which survives the crash...
Can I somehow clear the list of loaded plug-ins so that CopperPlug starts again?
I'll send you the crash report via email.
