Halo 3 forge problem?

[Patrick]

I just created an awesome map in forge, but I can't go back and edit it or play a custom game on it because it says that I'm prohibited from playing with user created content. What should I do?

Your XBL account is banned from custom content, you have to go to the dashboard and change this, you might have to make a new account because your account is probably under 18.

I believe to change the custom content restriction you have to go to family settings on your dash board.

good luck.
