Hi Wayne,
Our server logs show that the email was sent for the original purchase as well as the second one that you just tried. My guess is that the CartLoom mail is being rejected as spam or put into a spam folder. I’ve resent the serial numbers, but also included the serial number in the support email. If that doesn’t get through to you either, please let me know – I can send it here on the forum in a private message if need be.
I’ve also gone ahead and refunded one of the orders. 
Sorry for the delay, I’m prepping for a couple presentations at the WeaverSpace Conference this weekend and my support box is piling up a bit.
Isaiah
