Frozen screen. Menu does not load.

The game starts loading the mojang screen and the bar, so far so good. But after about 5 to 10 seconds after loading the game it freezes in the menu, animations and everything, making it impossible to click on play or any option. I know it's from the game since I can go to the main menu and everything. Everything works except the game. And before that did not happen. It should be noted that do not log in yet as I play in private (lonely)
