Please use the uninstall command found in Applications/Slate Digital/Virtual Buss Compressors. You will be asked to enter your system password. Text will not display when doing so.
To preserve user data, our un-installers will not remove some files from your computer. Occasionally, these files can cause problems when updating to a newer version of the plugin. We'll need to manually remove them to see if they are causing the problems you are experiencing.
Go to /Library/Application Support/Slate Digital
If you have created user presets, make a backup of them and delete the associated VBC folders.
Lastly, go to ~/Library/Application Support/Slate Digital and delete the settings file in the Virtual Buss Compressors folders. (There are four of them)
