Can't download rated M games - 360

Even though I turned 17 recently, I still can't download things on the marketplace such as rated M demos. I am under my own Adult account, but if it says 17+ for a reason...

Does anyone know what I should do? I know you can just create a different account, and make it 18+, but I hate having to wait to download something, and not play games(I want to get certain achievements, and play live, etc.)

 

You cant do anything until the date you entered says ur 18?

wat .

 

yeah, i did a little bit of research, and people said that. it just sucks that i have to wait another year if it were..

 

Why the fuck did you use your real birthday?

I'm like 72 according to my live account

 

Yes, because I knew beforehand. I just got the system nearly a half of a year ago. Thinking at the time I got the system, I would be able to play rated M games, and it would only take a few months until I turned 17. Did you even think about that? How would I have known that they don't allow it until you're 18? Frankly, it doesn't make sense.
