All emails were sent in a couple of hours after KSDF came out so, if you haven't received yours, the only possible reasons for this are:
- You haven't bought KSDF on our site
OR
- You used a different email that you are not checking
OR
- The email has been sent, but you haven't received it, most likely because it was filtered as Spam, either by your email program or your ISP
I checked your orders and, it's clearly the last case, since I can see your old order and the email is the same you used to register on the forum so, you can be sure the upgrade offer has been sent to you when KSDF for MSFS came out so, first check your Spam folder and, if you can't find it, contact support by EMAIL, and we'll send you another copy.
