Green Blinking Light, 0% used, Unk Temp

This morning, I was trying to logon to my 6TB MyBookLive on my mac via Finder (recently updated to Yosemite), and I got a message that said my username or password were wrong. I had to force mac shutdown because iTunes would not allow it to shutdown normally. I then turned on my Windows 7 PC (which has the WD Quickview), and could not logon to the dashboard, and now the QV says 0% used (have 251 GB of data) and UNK Temp, and the front and network lights are blinking green. 

What can I do? I’m afraid to shut it down (primarily if writing files), and I’ve never used the reset function. Help!

What happens when you try to manually log into the Dashboard by using the device’s name or IP address on a Web Browser using the Microsoft Windows 7 system? Does it reject your password? Does it kick you out?
