Problem confirming my email ...

I just signed up for a new account and I responded to the confirmation email (which is my gmail account) and it says:
"We were unable to confirm your email address. The validation email may have expired."
What should I do about this?

Since this, I am able to log in. I actually logged in using openID from my gmail account.

Let me know what I should do to correct this.

Thanks,
..Ed
