Game download getting stuck at 52%

So I went out and bought Destiny today and was pretty pumped to play it. But I never did because my Xbox has been stuck on 52% for about 4 hours. I've restarted my console and it would start installing again. But as soon as it reached 52% it says ready to launch or whatever. But I still can't do anything. It will not go past 52% install.

Anyone have any idea how I can fix this?
