The checkbox that asks if you're not a robot is an automated form of the reCAPTCHA program. If you fail it, it's suppose to show an image field with text that you need to type in to confirm you're not a robot.
If it's not working right for you, try disabling all plugins and extensions you might be using in your browser as they may be conflicting with the CAPTCHA program. Alternatively, you can also try registering from a different browser. For example, if you're currently trying to register using Google Chrome but are unable to, try Mozilla Firefox instead.
