Downloading Latest Data

I haven’t been able to play matchmaking on mcc since Saturday the 26th, everytime I go to “Find Game” I get the same message, downloading latest data.

I’m not new to this issue as I’ve played MCC since launch but all the normal solutions that usually work such as quitting the build, hard resetting my xbox, clearing my system cache or even completely unplugging my xbox from its power source haven’t worked.

Is my only solution to reinstall the whole game? Will that even work? My internet speed is average but it would take me two days to reinstall the whole 70gigs of MCC.

Help anyone?
