Help with firmware upgrade/replacement

Keep in mind that you can get free Customer Support from SanDisk, including a warranty replacement of the player if it is still under warranty (1 year in the U.S.) and faulty–SanDisk even covers the postage both ways.  SanDisk’s contact info.:  http://www.sandisk.com/about-sandisk/contact-us/.  Easiest to telephone them, and you can talk through any issue.  Good luck!
