I have been using your product for several months without a problem, but I seem to be having a problem with my account now. I have had 2 customers not receive their PIN numbers in an email after payment. On the most recent transaction the transaction showed up in my paypal account, but is not listed in the sales log on the e-junkie site and I cannot resend the email with the PIN in it since the system doesn't recognize that transaction number. I have not made any changes to my account in months other than adding new PIN numbers to the items. I can successfully send myself a free email via the admin tool. Please let me know how this problem can be fixed. Thanks
