Yamaha DTXpress/DTXplorer/DTXtreme

Hi All,
I just mailed my DTXpress II kit overseas from Asia to US.
After setting it up, the brain appears to be wiped.
When I turn it on, I get a clear screen with the "song" and "voice" 
lights lit up. Pressing any of the buttons does not do anything. 
Pressing "Page Up" and "Page Down" while I turn it on, does not reset 
it as the manual describes. Any suggestions on how to reset it or how 
to reload the info or who I need to talk to at Yamaha?
-JIM.
