Yamaha DTXpress/DTXplorer/DTXtreme

Hi!!

I posted a message earlier, but no one has replied.

Anyway,I seem to have a problem with sysex files. When I use the 
dtxpressions program, I find that, with everything connected, it 
quickly desplays the message " file sent!" on my computer screen.

However, Nothing happens on my dtxpress module at all. Can someone 
tell what I'm doing wrong? It would be very helpful if someone could 
get me out of this frustrating hole.

Peace out!!!
