ReadyShare Vault

Good evening.  I am running a C6300 cable modem/router, updated firmware, with 2 Windows 10 computers.  I am trying to access a ReadyShare Vault device: a WD 4TB MyBook with USB 3.0.  I was able to access the drive after reformatting from exFAT to NTFS, and I can move files from both computers to the drive.  But I'm unable to run a backup from either computer using the ReadyShare Vault software.  It creates the destination folder on the drive, then gives a "When you connect your drive" error message and goes no further.  The same is true for both computers.  I have uninstalled and reinstalled the software to no avail.  Any thoughts are much appreciated!

Also, is Genie technically required for ReadyShare vault to work?  Or is it just a nice-to-have way of troubeshooting and network mapping?
