Cannot get my WD HDTV Live to connect to my Imac

Can some one out there please help this is frustrating me!! I have brought a WD HDTV Live and set it all up have followed all the tutorials i can find to get all my settings right but it keeps telling me that it cannot connect??

I am concerned as i am reading that there are issues with it and Mountain Lion?? Is that correct? Has anyone got a fix that is simple???

Please help
