Downloading Latest Matchmaking Data

I’m having an issue in the MCC. Every time I try to search for an online game a box pops up that reads “Downloading latest matchmaking data. Please wait.” I’ve researched the issue and found multiple forum posts about the same issue, but none of the suggestions have worked for me. I’ve tried letting it sit on that screen, rebooting the console, clearing alternate MAC address, clearing persistent disc data, deleting my game data from the console and Xbox Live, removing my profile from the system, spamming the A-button, and even reinstalling the game. Nothing has worked.

I know it’s a known issue, but Xbox support told me to make a post here anyway. So if anyone has an idea as to how to fix the issue I would appreciate it. I’m open to trying just about anything short of getting a new Xbox.

Thanks.

the same for me

This is going to be one of thous issues where your now going to have to wait for a patch from 343i since i’m pretty sure that’s all the fixes you can do to resolve it. I think one will come soon after Halo 5 goes Gold or a few weeks after the launch of it.

Same thing for me. I hadn’t played HMCC for about a month then got on to play yesterday and have been stuck at the “Downloading Latest Data” screen when trying to play multiplayer. I’ve tried deleting my HMCC saved date, hard rebooting it to delete the cache, and opened the xbox port forwarding on my router to go from a “strict” NAT to now an “open” NAT. Hard rebooted it again and still nothing; I still get that damn “Downloading the latest matchmaking data. Please wait.” message! This is ridiculous and unacceptable.
