Sansa clip wont save settings.

lol you know what this thing is just wonky.    I changed mode,plugged,unplugged.   and after fianlly gettign songs to sync on to the device.   I double check the folders just to make sure they were actualy added.  what happens when i disconnect the device?   every song added to the sync list is gone.  As if i never added any music.    

How do I fix all this?
