Want to Sign up again with old email address

I closed my account to perform a reset of my GTD system, esp since I was not using it very much. I want to sign up with the same email address. I did the sign up page and got the intro email (with my new email address), but I cannot login to the site.

I get "Can you give that another whirl? (Make sure you're using the primary email address associated with your account.)" error.

Can you delete ALL instances of michaelramm[at]gmail[dot]com so that I can re-sign up and get to using Sandy again.

Thanks,
Michael
