My Book Essential won't back up files

My External Hard Drive, My Book Essential has quit backing up my files.  When I click on the WD smartware Icon, I get a message, "The type initializer for “WDSmartware.App threw an exception.”  I have Windows 8.1.  I can’t open the WD smartware app to do a manual back up.  Any ideas?

Hello,

I recommend you uninstall and reinstall WD Smartware. If the issue remains then contact WD support directly.
