I just installed Finale Version 25.3 on Windows 10 to evaluate the current version. I thought it was strange that the tutorial videos had no sound. Then I tested Finale playback and had no sound. Then I tried Spotify and I got music unavailable messages. Then I tried iTunes to test locally stored music files, but they wouldn't play. Rebooted the system, and iTunes and Spotify played as usual. Restarted Finale and playback didn't work. ITunes and Spotify didn't work. System sound testing produced no sound. Closed Finale, and then iTunes, Spotify, and system sound volume testing worked. What is going on with this version of Finale that takes over my sound system? Is it because this Finale installation is not yet authorized?
