Using ARIA player with Finale 2012 and GPO Full on Mac OSX Lion.

I am trying to build sections of instruments within ARIA player to play in unison from one line of notation in Finale. I am wanting to adjust the balance of each instrument in ARIA player, but Finale's settings always override what I have set in ARIA upon playback and reset the sliders. Is there a way to keep Finale from overriding my mixer settings in ARIA player so I can balance my sections appropriately?
