Is anyone else unable to access Waypoint form the in-game menu? Every time I try, my Xbox freezes up completely. The menu button on the controller becomes unresponsive, and the thing that works is the power button on the front of the machine.
Is it just me?
:EDIT: Deleting the WP xbox app, redownloading, loading the app, starting Halo 4 through the WP app, then starting the WP app from within Halo seems to have fixed this.
I had the same problem, go onto halo waypoint from your dashboard and download it again, it need an update or it will keep freezing
I deleted and reinstalled it. Still locking up. Anyone else still having problems even after the reinstall?
Fixed it. See OP.
now it’s locking up every time I try to exit. 
This happened to me. You have to go to your system memory and delete waypoint. Then redownload it through Halo 4. This will let you access it now.
Deleted WP. Installed through H4. Let me access through H4. Went to go back to H4 from WP. Locked up. I give up.

I got it to work for me. See my edit in the first post. Try redownloading from the dashboard, rather than from Halo’s menu. Don’t know if that matters or not, but I got it to work. See the OP.
We have seen this problem happen most frequently if you have installed Disk 1 of Halo 4 to your hard drive.
If this is the case for folks here, please just exit Halo 4 and launch Waypoint from the dashboard.
