1.) You have very old firmware. I’d suggest updating it. You can find the latest f/w version here.
2.) You should place audio book files in the AUDIOBOOKS folder of the player, not the MUSIC folder.
3.) Make sure to edit the ID3 tags on the audio book files so that the Genre field is “Audiobook”
4.) Please don’t resurrect and tack onto 6 year-old threads. Create a new one instead.
