Craftland.org

So i can,t add an account to my launcher, it says invaild username or password but im pretty sure i write it right cause on the website (craftland.org) and it Works. I have tryed several times and it still doesnt work, so do anyone know why?

The website and launcher login systems are not connected.
The launcher used your Minecraft email and password

Ohh! wow i didnt even notice the fact that it says it when you try to login. srry for the post tho!
