how can I pay my bill.
Hey Tara - you would have received an email with instructions to create your Self Serve profile when you activated last month. Looks like you didn't go through the link in that email, and tried to create a profile directly (which isn't possible for the initial set-up, unfortunately). I've just resent a profile creation email to your hotmail account - same as the one you're using here. Try registering by following the instructions in that email. Let us know if that works/you run into any issues again.
