TAP probably told you what was wrong with his, yours is likely the same issue. I don't know what he did to fix it, but he did and I received his payment immediately. A simple way to avoid that is to just copy and paste the email address that is provided (for future reference). Let me know as soon as you can get it straightened out.
You may be able to cancel the payment made erroneously. If so, just resend to the correct address. In any event, send the payment to the correct address or let me know to free up the spots - jp69l34rsss is then willing to pay for those spots.
