Freezing problem, please help!

Every time I launch Halo: TMCC off my dashboard it runs fine all the way to the “Press Menu Button” screen to enter the main menu, When I press the button it syncs Data and freezes for a good 2-3 minutes before it starts up again! And after every match or mission it freezes for the same amount of time before I can continue to play! Its very frustrating, please help!

I have gotten the “syncing data” message twice on start-up before I go to matchmaking but it only last 2-3 seconds…

I would suggest hard restarting your console by holding the power button down until it completely turns off then turning it back on.
