Basically when you click on "download", you have the option to pay to get the latest version. Usually there are 2 means of payment: Paypal and card. In this case there's just paypal. Unfortunately I don't know how you can activate this option on your side.
I'd also like to get this, but CC , no PayPal. Not sure how the creators get it done, but another creator [hotwife nextdoor] did it for me two days ago.
