Make sure you are using lowercase letters in both the user name and password. Make sure you are not blocking the resend of your user-name and password with a spam blocker. And lastly, your user-name and password are based upon the account that you gave when you made payment; if that has changed, or if it is not your own, you must email us with enough information so that we can track down your account and reset your user-name. We will need: The name payment was made under, the email address that was used to make your payment, and any other names or email addresses the account may be under. This is a line item search of over 500 users so we need as much to go on as possible.
