User blog:Hambo37mw2/Xbox help!

I was hoping you guys could help my with my Xbox. Every time I try to download something that is M-rated (demo's, add ons, ect..) a message appears that says this console is not permited to download content with this rating. I've made sure all of my console settings anf family settings are correct, so it should let me download M- rated content, but it still won't. I've also tried resetting all of my settings. Im not sure, but could it have anything to do with my age that I put in when I made my XBL account? Any suggestions?
