I have exactly the same problem. I am going completely nutty with it! I have now managed to lock myself out of my own disc! I and get in to the remote access and see the picture of the WD disc so he password works to get into the Cloud but not into my personal disc. I have
factory reset which took 24 hours
Force cylcled (taking power and lead off )
re booted router
rebooted Apple mac 10 6 x
all to no avail
My dashboard is now not longer accessible!
