Can't login to minecraft?

I have read the other questions but none of them can help me. I'm getting a message that says Unknown Username Or Password. I can't login to MInecraft.net, or the launcher to the game.

Are you registered in minecraft.net? If answer is yes try to restore your username next, make a new password. You can create another account too.
