Minecraft won't even load

Ever since the ender update Minecraft has been crashing constantly when I try to load the game, now it's at the point where I can't even play it at all. It can't get past the mojang logo . I don't know what the cause is but many other people have had the same problem, and there is probably more information on the forums. Please fix as I would like to be able to play the game. If you check on the store reviews you will see I'm not lying.
