Error: The Confirmation Email must match your Email Address

Located at www.missionAFRICA.com/staging

Steps to recreate.
1) Shop as a guest with no account previously created
2) Go to Checkout
3) Enter email (new customer radio button on), click continue
4) Enter billing information, click continue
5) Get error / account creation fails and am unable to get past this page.

I am able to create an account when I click login, but unable to click an account when I go to checkout. The only thing I can think of that is different in this installation is we have the AutomaticLogin mod.

Thanks for your help on this.
