I have been unable to launch BFD3 for some time now and found one thread where other users have had the same issue. I was advised by Joeface53 (inMusic Staff) to report it in here.
I assume you’ve already raised a support ticket as well, but I’ll try and help in the mean time.
Is your issue with Pro Tools as well? Could you tell me if you’re on mac or windows? What OS are you on? If you are on mac, do you have an intel or an apple silicon processor? What version of BFD3 are you on?
