Problem with digital download help??

My Forza 5 will not let me go on it because it will not load and i cannot uninstall it ether can someone help please/

Is there anything in your games and apps queue still showing less that 100%? Did you try to start playing before it was fully installed? Have you restarted your console? How long has it been trying to load and exactly what are you seeing on your screen? What exactly is happening when you try to uninstall it?
