radarshop , i'll suggest you uninstall the current MP3 Utilities & install another version, see if the problem still occurs.
If it still occurs, then you'll need to perform the Dead Player Recovery guide here

It is normal to brick your player whilst testing with various firmwares. And you may need to perform the recovery guide a few times.
