Downloading Latest Matchmaking Data

I’ve searched the internet, the halo subreddit, and this site, and haven’t found a solution for my problem. I can search for a game fine by myself, but whenever my brother joins me the “Downloading” message pops up every time. Also it pops up for him when he’s by himself, so I’m almost certain it’s a problem with his xbox/game. We’ve tried a hard reset of the xbox and that hasn’t worked. Any other suggestions?

when you figure it out lemme know. i have had this problem ever since the update. tried every suggestion i could find on the forums with no luck. my best guess is the update became corrupt somehow. the next thing i’m gonna try is a reinstall. i’m all out of tricks. did this also happen after an update for you brother?

it was indeed corrupt data. i deleted mcc and reinstalled with a friends copy on a usb hard drive and voila.
