Yamaha DTXpress/DTXplorer/DTXtreme

Good Day All!

My first post to the list so go easy on me. I recently decided it
was time to tinker with MIDI and/or atleast be able to download
.syx files into my DTXpress brain. So far I've been able to download
4 out of the 16 files available (BigMan, Daisykit, Looksee, & VMA).
The rest give me a "ERORR - Check Sum Error". Could the files be 
pooched or am I missing something here? Midi connections are ok, 
switch on the brain is set "MIDI" and I'm using DTXchange to download 
them in...

Any Ideas?

Can someone send me their copies of the .syx files available on 
DTXpressions, maybe mine are currupt?
