Stop sign next to Libraries

Hi.

Not to sure where on the forum to ask this? I've had a hunt around yet can't seem to find anything.

 

I have been using the Plex server running on an old PC for a few months now with no real problems. I watch the shows on an Xbox 360 using the built in video player on the xbox.

 

I can no longer view the libraries. There is a stop symbol next to the library, selecting the library does not list the shows it contains, intead it give you the option to play, which does nothing. I've attached a couple of photos to show what I'm seeing these are from when I connected to the Pi, yet the PC sever is doing the same. I think I did do an update to the server side, however I sure I was watching shows

 

I have a projector attached to the xbox and project the shows onto a wall.

 

Thinking it was the windows machine I have the plex server install on I uninstalled and reinstalled plex, still the same.

I've install the Plex server onto a Raspberry Pi2. This also does the same thing.

 

I have the UPnP enabled on ther router (a D-Link 3580L), I have disabled and then re-enabled the UPnP with no effect.

 

Ive install the PLex for Home Theater on a PC on the network and this plays the shows just fine.

 

Does anyone have any suggestions?

 

 

I need help with this issue as well.
