This is my second purchase today, for the same utility. Purchased under \"ian@cinnamoncafe.com\", had no end of problems. Once I paid the system did not let me in. Tried to change the password and it sent me 3 updates to the correct address, then informed me that the e-mail and password where both incorrect. Still have no joy. Decided to register again at ian@jonesi.demon.co.uk, and everything worked smoothly!
