M rated demos.

I'm 17, I used my real birthday when I made my XBL account. It won't let me download M rated demos, yet, I can walk into any store with my driver's license and buy an M rated game no problem. Is there a setting somewhere to fix this?

I think you have to go to family settings and change it, also I think why it wont download is because technically your account is a child account.

I never had a problem with downloading 18 rated demos?
