Looks like I have a similar issue.
No, you have an entirely different issue. The original poster purchased KMCO by mistake because he didn't realized that KMCO was selected when he started the purchase process, and his receipt shows KMCO so, it was just a purchase error.
If your receipt shows KJFK+KORD, it means you have purchased KJFK+KORD, no questions about it. In fact, I've checked your Order, and you HAVE purchased KJFK+KORD, as you intented to do so, there aren't any errors here.
Also, the activation status for your order also shows you have successfully activated KFJK, but you still haven't activated KORD. And, this is normal as well, because you have used the integrated purchase process, which means the activation is automatic for the FIRST product in the order, but you need to manually activate, using the "Register Serial" option, the 2nd one, which is KORD.
So, I guess the only problem you have, is that you simply haven't selected KORD before choosing the "Register Serial" option to activate KORD, the cursor was probably on KMCO, that's why you might have seen a message about ASKING if you wanted to activate KMCO, at that point you might have aborted it, but that wouldn't mean you *purchased* KMCO, it simply meant that it was asking you if you wanted to activate KMCO, but you would get an error in any case, if you tried to activate KMCO with a KORD serial.
So, simply selected KORD before selecting the "Register Serial" button, and insert the KORD Serial Number as shown on your email receipt.
