Hi Jen
We provide free upgrade for one year for each purchase. So if you purchase the extension in less than one year, you will get free upgrade.
Do you see your order when access to My Downloads menu item ? If you don't see it, please submit a support ticket letting me know Paypal Transaction ID of your purchase so that I can find order, assign it to your account and you can download it (if your subscription is still active)
Regards,
Tuan
