Not anywhere near the topic of networking.
Usually with MP3 players you can only do two things to try to resolve any problem the player may have: format or upgrade the firmware. The firmware can be downloaded from the manufacturer's website. I tried to do some research but couldn't find anything on it, nor could I find the manufacturer's website. In this case, contact the manufacturer.
Consumer electronic specific forums do exist. In such a forum, the users would be able to tell you more information.
