Confused!

I recently installed Serviio on my computer. Initially, I was able to successfully connect to my Samsung series D televison. Now I can't and I don't know what to do. My TV shows up under the status tab on the console, and the light is green (active). What puzzles me is that I haven't changed anything. The tv connect with AllShare without any problem. I'm not very skilled with computers, but would appreciate any help. thanks in advance.
