You can request that the system resend your confirmation email.
# From the Login screen, click "Forgot your passphrase?"
# The "Forgot your passphrase?" screen, click the "Didn't receive confirmation instructions?" link
# On the "Resend Confirmation" page, carefully enter your email address and click the "Resend confirmation instructions" button.
It is also possible that there was a typo in your email address when you set up your account. In that event, the system will not permit you to resend the confirmation email as it will not recognize your email address. In this case, you will need to set up a new account.
Please let us know if this resolves your problem.
