I recently had this error message and now the BC Manager wont open. I was working without problems uptil now.
When i make a new user (OSX) then i can start the software but otherwise not. I have reinstaller the software, removed the programfiles with AppCleaner and i have trashed the midi preference files - all with no succes :-(
Macbook Pro 2012, OSX 10.12.5, BC Manager 126.96.36.199
Any ideas anyone ?
