Disklavier

A plea for help! The problem: piano with Disklavier DKC100R will not play a song coming from Finale 2011.  Some background: I'm new to the midi process, but have done considerable homework.  Here's what I've done to solve the problem:  purchased a midi interface (Cakewalk by Roland UM-1G) installed drivers, connected the UM-1G to the MacBook Pro laptop and to the disklavier DKC 100R, performed a midi test (pushed the test button on side of UM-1G unit and the piano played a note).  Referred to the Yamaha Advanced Operation Manual (disklavier II) Chapter 15 pg 97, "Using the Disklavier Piano with a MIDI Sequencer" performed steps 1-9 in Disklavier control unit DKC100R.  In Finale 2011 > Midi/Audio > Device Setup > Midi/Internal Speaker Setup with the following: Midi System - CoreMidi, Playback - Midi System, Input - UM-1G, Output - UM-1G, Receive Midi Sync From - UM-1G, Send Midi Sync To - UM-1G. In Finale 2011 > Windows > Instrument List with the following: Staff 1 - Grand Piano - Channel 1, Staff 2 - Grand Piano - Channel 1. Mute None, No Solo.
With the above setup and connected to an electric keyboard (unrelated to the Disklavier and piano) the song plays, but for some reason I can't get the Disklavier settings and/or other combination of settings to facilitate play back on the piano.  I would greatly appreciate any advice that could be provided - I'm at the end of my rope.  Leon
