I can't find the solution to this anywhere. I recently got movie studio 13 and in one of my projects the audio on 2 tracks got inaudibly quiet, but the master volume keeps registering around -3db. I can only hear it when I pan the volume. It now does this for all of my projects. I have restored default settings multiple times in my preferences and that doesn't help. I see where others have done this too, but I don't see any answers to this other than one guy re-installed. Anyone know what I hit to screw this up?
