Paypal sometimes places online payments on hold for security review. This review process may take up to two business days. Also, eCheck payments may take up to four business days to clear.
Your subscription cannot be activated until Paypal releases and clears your payment. You should be notified by Paypal as to your payment status.
If, however, your online payment has cleared but you still cannot download your subscription materials, please contact customer support as soon as possible.
