Question about Loading up the game

Normally, when I push the menu button to load up MCC the game looks like it freezes, then after about 40 seconds it loads up the main menu. When I took my box to my friend’s house, this wasn’t an issue and the game started up properly. Now, I’m back at my house and it has started doing the freezing thing after I push the menu button again. Its pretty weird. Any ideas on how to fix this? Anyone else experiencing this problem?

have tried resetting modem/router, clearing saved data on the xbox, uninstalling/reinstalling the game, clearing alternative MAC, and cold restart. this is irritating.
