At the end of last school year, I used the most recent version of Finale to create Boomwhacker music for my students. I even transcribed "In the Hall of the Mountain King" for my Junior High class. Finale and Garritan made the preview playback sound amazing, and it helped me hear what I needed to hear as far as balancing the sounds.

Today, as the new school year gears up, I look forward to using Finale to create more Boomwhacker scores. However, when I went to input music for Boomwhackers in today, all the notes were silent. Playback was silent. No sound files or record of any sound files for Boomwhacker notes exists any longer on my iMac. I've not updated the operating system since May, nor have I gone messing around in Finale's or Garritan's folders on my computer.

Please help. I feel like I'm going crazy, and I really need to hear my Boomwhacker music before I can give it to my students. What can I do to restore the sounds?

I'm running Finale 25 on Mac 10.13.6
