Hi,
I am sorry that those crashes. We need to analyse your settings. The VST Connect Performer apps has saved 3 files for the VST/3 handling. There are stored here
/Users/username/Library/Application Support/Steinberg/VSTConnectPerformer
The files are
Vst2Folder.xml
Vst2Plugins.xml
Vst3Plugins.xml
Can you please zip this VSTConnectPerformer folder and send it to me : m.spork (at) steinberg.de
Thank you,
Michael.
