I've got problem with sound module Reely double boost sound simulation pro
When I connect it properly to the model (receiver, ESC and battery) module is ON (but without any ON sound) , but it is not working good - there is no sound when I try it with throttle ... even no sound when I volume Up or Down.

I have connected it to the PC by the USB dongle and there is screen

As You can see device is recognized, but there is no sound files on it.

When I try to upload sound file - there is no space to write sounds:

When I choose Configuration of the module, there is a result:
Device firmware is invalid. Please Upgrade firmware first

How to do it ? And from where I can get the firmware ???

thanks for help
