Greetings Finale Community,

 I use Finale 2012, and since a recent upgrade of my operating system (Yosemite 10.10.5) - I am not able to effectively use the playback function in Finale.  Upon attempting to utilize playback function, Finale goes into a "freeze-crash-burn" cycle that I'm unable to avoid.  Consequently, I've continued to use Finale without the Playback function.  I can no longer avoid this problem.  Any advice/assistance would be greatly appreciated.
