I Have A Minecraft Account But Will Only Play In Demo?

I've Had An Account For Very Long, But I Changed My Email And Now It Only Says "Play Demo!". What Do I Do?

You sure youre not playing in the browser?
Did you change your email in the account?

Consider Contacting Mojang On Their Support Page. It May Help You Find What You Are Looking For, You Can Also Send Them An Email. Starting Each Word With A Captital Is Really Annoying And Is Hard Too Do, No Offense Though.
