Let's refresh this thread!!
Same thing started to happening to me - in tuesday ,it worked ,and I've made backup manually by pressing "Back up now". Today ,I've tried and nothing happens ,just as syntax said.
Then I reseted backup in registry ,but no luck! Those two buttons won't react!!
I've made some progress now ,I clicked on Autoplay options on backup drive and set up backup ,and ,it's working now ,but still ,View Details button isn't working ,and I'll see what will happen with "Back up now" when backup ends!!
Edit: None of the buttons on right side of Backup and Restore panel isn't working except Recover my files.
