I have the PC Editor and some time ago, it stopped working. The Editor Software is working. As soon as I turn on the 8X, I get this message:

When I start the PC editor, the In/Out boxes on the Editor do not display the "arranger" as they used to. The PC can't "see" the 8X.
I removed the 8X cover and traced out the PC cable. I get continuity from all 4 connections on the USB plug at the end of the cable all the way through to the 4 solder connections on the Printed Circuit board inside the 8X. I suppose there is a hardware problem somewhere on the circuit board. I have done a full Factory Reset and reloaded all the "Sets" and "UPG's". The problem is still there. The 8X works fine.
I have lived with this for some time and have learned to use the "on screen" menus on the 8X.
My question is:
Is there any function that can be done with the PC software editor, that I can not do with the "on board" 8X editor?
