Ever since the Reach update MCC Will not load for me at all. It either gives me the took to long to start error, or it lags and freezes during the initial loading screen (Xbox game studios and 343 logo). After 20 minutes the closest I’ve got was a black screen with the MCC logo in the right corner and then it just dashboards itself after about 10 minutes. I’ve reset my Xbox multiple times, I’ve uninstalled and reinstalled the game, I have moved it from my external back to my internal hard drive and even factory reset my Xbox and nothing has worked. I would appreciate Someone from 343 at least acknowledge this problem.
