Hi,it's not updated that's why . You need to upgrade with firmware.
Follow this instruction:
Things You'll Need:
-
A MP3 Player
-
A Computer with an Internet Connection
Verify that the player is fully charged.
Verify the the player is unplugged from your computer.
Go to the Mp3 support site, linked below, select your player, and
download the Sansa Firmware Updater software. Follow the instructions
for installing it on your computer. If you need them, you may also
download user manuals for your or watch how-to videos on updating the
firmware.
Put the player in MSC mode. Go to the settings menu, select the USB
submenu, and then select MSC. Some players with early firmwares do not
have the USB options in the menu. If this is the case with your device,
then there is another way to force it into MSC mode: Put the device in
"hold" mode by sliding the hold switch until orange is visible. Next,
press and hold the left (rewind) button until the screen changes. Go to
the next step.
Plug your mp3 player into your computer and wait. The Firmware
updater should launch automatically. Follow the prompts to update your
player. Be certain not to unplug your player until the updater is
finished. The software will tell you when it is safe to disconnect.
