Most likely, you did not complete the subscription process properly. Once you enter your information and click subscribe, our system makes a number of tests of your information. It checks to make sure that your credit card information is valid, that the address you entered matches the billing address on your credit card, and that all fields have information in them.
If any of this information is missing or incorrect when you press the subscribe button, you are returned to the form to make corrections. We have observed that some people think, upon being returned to this form, that they have actually completed the subscription process. They haven't, and as a result do not receive a confirmation email or password.
Every successful subscription will lead to a confirmation page with your billing information, your user name, and your password. If you did not see such a page, your subscription was not completed, and you were not billed. You may subscribe again, using care to read and print the confirmation email. If you accidentally are billed twice, please contact us and we will credit your account at once.
