MCC is not loading, damn.

so before I continue, I don’t know what this is, it happens with fifa 15 but not with downloaded trials. Basically when I start the game up, it has static screen then Microsoft studios and 343 logo and whatnot, then I press the ‘=’ button and that repeated rock screen carries on forever, and I’m not being an impatient kid, I went and watched Wimbledon on hdmi2 and it hadn’t loaded in 3 hours, is this a console bug or a game bug? The files cant be corrupt can they, as I can load the first few stuff. Idk, please help.
