Disklavier

well, i did a stupid thing...
 i got button happy and pressed a bunch of buttons and now my DSR does not 
allow me to hear anything that i have recorded!  the only thing that i can 
atribute it to is when i pressed reset which apparently reset it to default 
settings?  so i have been trying to reset to whatever i had before when it 
worked, but  to no avail. 
 any help would be wonderful!
does this mean that the upgrade flash is lost as well?  i can't seem to tell.
please someone advise me...thanks!
