Halo 3 Maps Problem - Xbox 360?

[Unreal]

I just bought a new Xbox 360 Arcade, because my Xbox 360 Pro broke, and now on Halo 3 it wont load the maps
I have the same hard drive.
I am on my profile right now, and connected wirelessly.
The maps cost money so I dont want to pay for them again.

Have you connected online with your profile yet? That might be what you need to do, even if its on the same hard drive, just a diff console. Some games like rockband require an internet connection for you to be able to use the downloaded content. If you have connected to the net allready and it is still giving you problems, try redownloading the maps, this should fix it. It will take a while, but it will do the trick almost 100% sure.
