I very recently purchased a license through PayPal but have not received a license yet. I can access an old listing of licenses but there is no new license.
Check in your spam / junkmail folder if you haven’t already just incase its gone there.
If nothing in there, try going to the following webpage and enter your email address you registered with and you should get your license key emailed.
Failing that, id suggest to email [email protected] who will be able to assist you.
