Serviio Not Working Properly

Hey everyone, I have a strange problem with Serviio ond my Samsung UA46ES5600.
When I start up my computer Serviio starts and is always detected by the TV, however, it does not always work.
I know it is going to work if the icon shown for Serviio on the TV is the yellow Serviio icon, but if it is not that it displays the standard UPNP icon but still says Serviio. When it is like this, I can still browse the folders on the TV, but it is very slow, and when I try to play something, it says that the format is not supported.
To fix it, the only way is to restart my whole PC. I have tried only restarting the Serviio services but this does not help.
It's very frustrating, I hope someone can help me.
