there are literally hundreds of posts regarding this with the WD staff closing the thread when an update is released, there is a link below to an alternative called genie timeline which i have downloaded the free version and not tried, so make your own mind up,
it seems the most popular smartware is 1.4.1 that people downgrade to if you can find a download ,
i have enailed WD support but there website enquiry form seemed to error everytime so not even sure they got it
