TV Live Hub Wont map drive. Says No Network Share available

I’ve just bought a new WD Live TV Hub. Powered it on, connected it though the Ethernet cable to my Router. When I run WD Discovery I can see the WD Live Drive but when i click Map Network Drive it tells me 'No Network Share Available.

Im using Window 7 Home. Any idears any one? I can see the Device in my net work map but cont creat a drive letter.

Try using WDlink instead.
