Newbie needs help with Kodi

I just bought a Amazon stick with fully loaded Kodi. I was getting a lot of digitizing. By mistake I “cleared data” instead of “clear cache” I went on line and loaded my own video-add-ons of my favorites. One of the channels I love to watch is Fox news live. I uploaded “cchannel” but my streaming is very poor. It pauses every 5 seconds. It is irritating.
Does anyone have any ideas on how to get Fox news live?
If you do please send me links and instructions on what to do.

Thank you very much.
