Problems with Signups

Hello... All of the sudden I am starting to having issues with the signup process within Pro-Sites. I think this happened after I deleted a few test accounts... I go through the signup process and when I click on the email link, the page comes up problem with this account. THe account does not seem to be there... I am giving the signup the option to upgrade during signup. And the link that is being sent is not redirecting to the upgrade... I have noticed the URL after I verify my email has something like "www.mydomain.com/pro-site" even though the account is not a proaccount.. Not sure if this is the issue but letting you know...
Thanks Tim
