Problem confirming my email

I just signed up for a new account. However, upon responding to the confirmation email, a message appears that says, "We were unable to confirm your email address. The validation email may have expired."

A quick search suggested this:
You should be about to go back to your list of email addresses (Account > Email addresses) and click 'resend confirmation' for the email address in question.

However, when I go to Email Addresses, there is no "Resend Confirmation" link. What should I do?
