Nokia Lumia 520 - Unable to download Whatsapp

Hi,
I recently purchased "Nokia Lumia 520". When i try to download download "Whatsapp" then it's giving error as "My Family setup needed".

I am a adult and age mentioned as 29 in Microsoft registration.

Can you please help to guide to me to install the Whatsapps in my mobile.

Thanks in advance
