Media server's not showing up

Hey, I recently bought the WD TV Live for my home theater system. My problem is that the dlna servers don’t show up anymore. I think it happened after I upgraded the firmware. I stream my content from my Windows Home Server; I have tried using Tversity, Serviio and PS3Media Server but none of them have shown up. When I first got the TV Live all of the media servers have worked. I have tried resetting the device many times but that does nothing. I am able to access web content and network shares of my Win 7 machines. Lastly the TV Live is connected over Cat5e Ethernet cable. Should I downgrade the firmware? What should I do?
