ok, you set the wrong Date of Birth David, and it sees you as under 18
To get parental consent is a very long process, and will often be rejected by Microsoft.
I advise you to make a new account as you just made this one.
It is free. Just click on my link below to make it.https://signup.live.com/
It is critical to specify the correct birthdate as they use this to check that your over 18.
Once created you can then use this new account without hassles.
If you are determine to use this account you already made, I can gicve the instructions for the parental consent, but it is a difficult process (as it most with Microsoft). Just let me know.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service, that would be greatly appreciated.
