Halo 4: Champions Bundle Help

[Melody]

Sorry if this has been posted before, as i'm sure it most likely has. I can't seem to load the map data, it keeps giving me a error. All the skins and armour works perfectly, am I doing something wrong?

I think first you need to find Halo 4 on your storage device, look for the champion bundle, delete it, find it again on the marketplace and re-download it. I think that would work but don't do this just incase I'm wrong, maybe someone on here can verify that this is how you solve the issue.
