Look in the Cellular tab of your Settings app. Scroll down until you find the block titled "Use Cellular Data For." If the app that you are trying to use is listed there ensure it is turned ON.
If that helps, yay. If not, holler back and we'll take another try at it.
Thanks for the swift reply. I've gone in to cellular and scrolled down the the app it's saying that use cellular data is turned on but it keeps showing that thing every time I try and watch the sports channel :s
