HELP with Passport for Mac

I am trying to back-up my pictures onto the My Passport.  It only worked the first time I plugged it in.  Now, the WD Smartware only allows me to use the Home and Settings tab.  It will not let me use the back-up or retrieve tabs.  My already saved pictures come up in Finder.  Please help.  I am about to go buy another brand if I cannot solve this.  This is the second WD Passport I have bought and none of them will let me backup files more than one time, which is ridiculous.  Any help to solve this issue is greatly appreciated.  

Thank you,

Mel

Hi FrogMel, Welcome to the Community. Can you share your Passport drive model numer? Smartware is not compatible with the latest version.
