WDTV Won't Read My Book Live

I have the white 2TB My Book Live; I can access it wirelessly over my home network to add movies or edit; but when I turn to my TV and try to read the drive via the WDTV Live device, it’s stopped showing up. Was intermittent for a while, now she won’t read at all. And yet it’s still on the network. 

Double/Triple checked connections, power supply, ethernet, reset reset reset. Now I can’t watch Xanadu and I’m sad. 

Hello, make sure the WDTV and the My Book live are part of the same workgroup. If the problem continues, try restarting the Router and the WDTV.
