My experience with online registration is that it's great, but sometimes has a few bugs when first applied to an existing system. When in doubt, contact the registrar. I've shown as being registered before, but not paid, and vice-versa. The registrar got it all straightened out quickly and all was cool. It's really great on the registrars and the entrants when all that stuff is taken care of before registration. And we all know what kind of mess that can be at the ARRC with that large crowd!
