Emu XL-7 & MP-7 User's Group

Hi all,
First of all let me say that i am thankful for this group because it 
is so helpful for someone like myself!!!
Anyway my story goes like this; I am trying to load O.S. 1.32 into 
my MP-7 but it is not working!!!!!!!!!!!!
1st i load e-loader 1.1 then i hold down buttons audition and home 
on mp-7 get the needed o.s. file click on download o.s. file to 
target........ then i get a MIDI communication error saying no 
device is detected. Is there a way to detect if my midi connections 
are setup properly? Is there a way to tell if my system is sending 
and recieving midi information? 
Thanks to all....
