Sansa Fuze Firmware Update 01.02.31 & 02.03.33

I need help.  I cannot get the updater to work so I tried the manual update, but the unzipped files will not go into the sansa fuze file.  I get the red circle with the slash mark.  I have only had this a month and it is not working.  It freezes and now it just jumps from on file to the other continuously.  (audiobooks.)  Please help
