Passport Essential Unable to Back-up

I haven’t backed up my computer files for several months and now I am unable to do so.  When I view the back-up page it show that 0 files are backed up and although the back-up button is available, clicking it does nothing.

there is a message to download an update for WD, but I haven’t so far —a little nervous to do anything.  Also, just a note: I have Norton Security Suite as part of Comcast Internet and wonder if that may be interfering.

thanks-Kathy

problem is solved.  I went ahead and downloaded the updates and all is well!  thanks! :)    K
