Streaming on home network to iPad

I downloaded the free version and was able to stream movies to my iPad in the house flawlessly. Now all of a sudden I can no longer do so. All the files are mp4 on my pc. When I look at the status page of tversity it is not even showing iPad as a device, however, it still works fine with my ps3 and I am able to transfer the port and use the procedure for streaming via web with a different ip address. It was much smoother stream using the machines ip address plus:41952 in safari,but now I can’t anymore. It now says safari can’t connect because server stopped responding and won’t link iPad as a device. Can anyone help?
