For some reason my registration link didn't work, I can sign in, but it always tells me to confirm my registration. I clicked the link but it gives me this message saying that I've either already confirmed my registration or that my link is incorrect, no idea...
3. A window will pop up. In that window, click the link that says "You did not receive the confirmation email?"
4. Input your e-mail address, and the confirmation e-mail should be resent.
If this still does not work, please try creating your account with an alternative e-mail. Please bear in mind that some email providers may flag account confirmation emails as spam, so be certain to check in your spam folder for the email.
