Have you created an account on The Atlas. Accounts there are not the same as on here, and making a forum account doesn't already mean you have an account on the rest of the website. I suspect that may be your problem.
No and that one of my problems. I try to login with my username and hoping for new password and I got this message.
Error: That username is not registered.
Here my email account to send the email reporting this email@example.com
