Right, but getting activation emails out does matter. I think the previous owner of the server IP got blacklisted. I had gotten the previous server to where emails would go through yahoo mail, hotmail, etc., but now they all get spam filtered. With some email services, spam filtering eats the emails completely, and you never even see them. What do you use for email (what's after the @ in your email address?)
To have another activation email sent, simply fill out all the same information you did previously. If the account hasn't been activated yet, it will just overwrite it then generate and send a new activation code. If you still don't receive an activation email, you might try contacting your email provider, and see if you can get them to allow emails from dplogin.com [70.85.9.178].
