Yamaha DTXpress/DTXplorer/DTXtreme

Hi I`m new to both this group and the DTX 1 module,I tried using the 
DTXchange software and could save my factory presets fine following 
the info provided to .sys format but when trying to send a .sys file 
to my user spaces the module just sits there NOT saying "BULK 
Receiving, please wait..." so i presume its not being detected by my 
module ...the midi leads are connected properly ie...in-out out-in 
and I checked the host select switch and the internal midi 
parameters were as they should be and they still don't send so any 
ideas/input would be a great help.
