M250 not Decoding Audible.com File

Hello.

If I stop reading an Audible.com book with my M250, turn it off, and then turn it on later, pressing the “Play” button to resume reading causes the player to make chirping, gurgling sounds as if it had forgotten how to decode or unscramble the file. If I press “rewind” or “fast forward,” everything returns to normal. I don’t notice this oddity until I am well into the file. Has anyone else had this problem? If so, is there a fix?

Thank you for all help.
