How to get the multiplayer function to work?

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, 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.
