I had the same problem. I first tried to reformat the player using Windows.
1-Click on My Computer.
2-Right click on the drive that is the player.
3-Select "format".
4-Click "start".
This did not work for my player. I contacted the manufacturer via their website and they emailed me a program to re-install the firmware. The software for the player was basically corrupted. They sent instructions on how to install the software they sent.
