I am using Finale on a Windows 7 OS. I assembled a small jazz ensamble instead of using any of the preset ones. When I was almost finished I decided to swap out the acoustic guitar for Vibes using ScoreManager. When the viberaphone part came in, it didn't have any sound. No sound when I put notes in the stave, nor in playback. The same thing happened a while back when I accidentally deleated a violin stave from a piece and used ScoreManager to put another back in. I am fairly new to Finale and this is the biggest piece I have done so far. I do not know if there is something in prefrences, or if this is a glitch I can fix, or if my program is bugged.
