I am on v25 Mac now and I still get the same dreaded playback window issue I got since working with Finale '97. You can't be serious.
"Please enter a number between 1 and 1" in the playback controls.
I've been over this with the German support (formerly had German versions thru Klemm) and back then they told me it has something to do with the playback settings. BUT: if there are playback settings and I'd like to use them the way I need them to be, they should work. They should not give me error messages that make no sense at all.
