I have a MacBook Pro and recently upgraded to the most recent Finale.  I have tried to load the instruments in the normal way, but they will not play.  To hear my score I have to revert to Smartmusic sounds.  I have followed the instructions online, but nothing works.  Also, I am told that after I choose the Sound Map Priority, I am to select "play thru VST."  That option is not even listed under MIDI/Audio.  Any help would be appreciated.  Now I'm getting this error message from Aria Player.
