Confirmation email won't "confirm"

I click on "Resend Email." Then I receive a "Welcome Aboard" email with an "Activate Account" button, which I click, which takes me to my Account Settings page...which has a banner across the bottom which reads:

"Thank you for registering with Arduino! Please follow the instructions on the confirmation email to verify your email address and activate the account."

(which also has a 'Resend Email' label on it)

I had been using the website for a couple of days without getting this confirmation message, but now it's back and it won't go away no matter how many times I resend the email and click the Activation button.

I'm using the latest version of Firefox on Win 7 x64 Pro

Thank you,
