Plex content source disconnected

Thanks but I get nothing when I select Windows Shares - even though I have enabled it in Settings. Just an arrow that goes round and round.

There must be something wrong with my WDTV Live as when I connected selected Plex using SBMC on my old jailbroken Apple TV, the movies played fine.

Does anyone else have any thoughts as I’d rather use my WDTV because I prefer the interface and it also plays Netflix

Thanks
