Daniel wrote back after checking the files. All I needed to do was go to Play > Apply Playback Template and click on the line that was already highlighted (“NotePerformer”). Then it works.
When I had looked at that dialog box yesterday, I thought since NotePerformer was already highlighted that it was already selected, so it never occurred to me to click it again to re-apply it.
So, yes, Derrek, you were right.
