Samgsung Smart TV~ Serviio not working

Hey guys! Quick problem here.
I'd been using Serviio for about a year now and it's been great, never had an issue until last month we were sent a new router by our internet provider~ Ever since setting it up, I can't get Serviio to work at all!
Even when I do a fresh reinstall, on the Status screen it's only bringing up one listed device that it says is unrecognised (Orange light). When I first got Serviio, everything just worked perfectly without me having to really do anything but now that's all I get.
Is there any kind of set-up or anything I could try? I love Serviio and don't want to lose it >.<
