I have problem to update operative system and the new sounds..
And I do everything according to instruction:
Installing the new Operating System:
1) Insert the USB storage device containing the [M3SYS] folder.
2) Turn the M3's power ON.
3) Select GLOBAL mode and execute the command "Update System Software" from the upper RH Page menu.
I do all this but it says:
"File/path not found"
I have tried 3 different USB devices (FAT 32), and no result at all??????!?!?!

Please could anyone help me?
