It keeps telling me to re-enter my User ID and password.
Typograhical errors are the most common occurence, especially with passwords.
Make absolutely sure that you have entered your password correctly. Remember that passwords are case sensitive. If you have capital letters in your password, they MUST be capitalized. That is only included as your email address. If you have just set up a new account, remember that new account information is entered between the hours of 12 noon and 1 p.m., and 5 p.m. and 6 p.m.
