Why am I looking at a black screen?

Seems to pick and choose when it wants to work for me. Ill be at home or at school with perfect connection and still be stuck on the loading screen. On top of that it always freezes when loading a commercial. I dont pay to look at a black screen and a loading circle so please fix it
