Disklavier

This is my first post so please excuse any clumsiness stating 
funcitons of the piano.

I have a DC3Pro with a DKC500RW control unit.  I also have the 
DCD1.  

The technician came and installed the EMK1 a couple days ago.  Today 
I tried to play from a diskette and the piano does not play.  The 
accompanyment plays fine but the keys do not move.

The cables are all correctly connected.  The problem is in the 
configuration of the new DKC500RW board to recognize the piano.

I have searched the Yamaha site but can not find any insturctions to 
do the configuration.  

I have out of town guests comming and want to play and record on the 
piano tomorrow.

Help ASAP!
