My WD Passport Ultra wont back up files via the schedule

I have recently bought a WD passport ultra 2TB, to use with my DELL Inspiron 15, running windows 10. I have already spoken to WD support who advised to download the latest backup sorftware from the WD site, which I did.
However, the problem still persists. As soon as I instigate a back up, I get a message within 2 to 3 seconds that says that it has been unable to download certain files and the whole process stops. I can drag and drop ok, but I want the schedule to do it automatically. Anyone any ideas.?

Hi, which backup software did you download?

Just WD backup on the WD support site.

Download the WD Smartware that software will allow you to set a schedule for backups and it should work with your drive.
