Can't create a world

I was playing Minecraft and I wanted to create a new world, so I went to the create page. Above the options of creation, it says "You cannot play multiplayer due to parental control." So I updated it so that I could play multiplayer. Went to the create page again. Same message. On top of that, the create button won't work. I can't even select the button cause it's just grayed out and doesn't let me create a new world. It's been working like this for a while now. I heard from some people that if you delete Minecraft and download it again, it would work. So I uninstalled it, and downloaded it again. Same message. Same problem.
