Can't set up device

Hello I am having a lot of difficulty setting up my WD TV live device.

I have the WDTV live plugged into my TV. My wireless router is in a separate room. My PC is upstairs. I have a devolo dLAN 200 AV plugged into the WDTV, and another plugged into my PC. The lights are on on both devices. When I try to create a wired network it can’t detect one, but it will detect my media library. However when I try to play any file on it it says ‘browse error. content not available,’ I am using firmware 1.07.18. I have tinkered with my windows 7 settings to allow sharing and have turned off passwords. I have tried resettting, and ahve not other devices to try it with. Any help would be greatly appreciated
