Find Drive or in the alternative Access Drive

My drive was connected to my router and working fine. It had to be unplugged to move some things. When I plugged it back in and ran discovery the program found no network drives. I rebooted but that didn’t help. 

I am running Windows 7 but running discovery in XP service pack 2 compatibility. Still didn’t work. 

How can I find the drive or in the alternative access the contents and move them to my new 2  TB My Book?

I think this effectively eliminates the TV Live from my future. I read in another post there are firmware issues and WD doesn’t seem to be fixing them.
