How to get the multiplayer function to work?

Hi,
When im trying to connect to multiplayer in forza 7 (pc) i dont get it to work. It says “this feature is blocked per your Xbox live parental Control settings”. I would be very grateful if someone could guide me in this matter!

Access your Xbox Live Account via https://account.xbox.com, go into the Privacy and Online Safety area and enable the setting that allows you to join multiplayer games. If you account is a Child one, then you will have to get your parent to make this change.
