FourFoxes, I was in the same boat as you - had registered a few days before I got the email. Because most of my hits were from before I got the email, I worried (though I had a screenshot saying I was registered, or "thanks for registering"), so I called customer service and found out I was registered exactly when I thought and not when the email came. So if you're worried, you could definitely call US. I'm sure you'll be fine, though.
