Lost....

I got my K-5 yesterday and was trying to load some programs into it 
using a couple of sys ex utilities that I have including the one 
offered on here in the files section. I use a usb midi connector to go 
from my computer to the K-5 as I do with my other synths but cannot get 
the K-5 to accept any programs. I connected the K-5 to one of my other 
synts to make sure that the midi in was working and it is, the system 
exclusive part is also turned on on the program. Any ideas as to what 
I'm doing wrong? Thanks,Scott
