Hello Ramirus,

It looks like this is installed on your internal drive on the Mac computer, is that correct? If that is correct, when you say you reinstalled, did you delete the entire Band-in-a-Box folder by moving it to trash first to ensure a clean state before the reinstall (if you save any personal song files in there, which we don't necessarily recommend, be sure to move them out of there to a safe location first)? Sometimes just reinstalling the program overtop of an existing copy when the program hasn't be cleared off the system won't fix the issue. Also what version year of the program are you using?

Let us know if you are still needing assistance with this!


Cheers,
Ember
