My younger brother created our xbox live account back in middle school and he is now 17 and I still get this message every time I try to download anything from the marketplace that is rated M or over... HE IS 17 NOW!
But his age shouldn't matter because I took over the account payments from my parents last year and changed all the account info and I am 19!
There is no reason I should be recieving this message at all! FIX IT!
