Have just purchased and set up new My Passport portable drive. Set up and run run first backup successfully but at the end I am unable to open WD Backup. This happened previously with older (2014) passport ultra and I assumed there was a software conflict hence purchased new my passport portable. I am tearing my hair out here as the same problem has now occurred and I have no idea what is causing it. I run Windows 10 on Dell laptop and nothing has changed recently in terms of new software or any other changes to the operating system other than I guess regular Microsoft and other possibly software updates? All previous older WD software was removed before downloading new versions too? I have reloaded WD Backup again and the same applies so am at a complete loss as to what is happening? Help anyone?
