This is only running intermittently. Usually it hangs looking for my My Cloud Mirror.
You may try uninstalling and installing the software. Also, please ensure that your operating system is updated to the latest version. Refer to the link below:
My computers are both running current (win 7) os. I uninstalled and reinstalled the latest My Cloud software. It finds the device the first time it runs, but not thereafter. All other WD software works fine.
Any other suggestions?
