I did purchase the supporter edition: it took me 1:15 hours of constant "reload"ing of the websites but eventually got through.
Paid with PayPal, and then received the PayPal confirmation forthwith and then 6 minutes later received the confirmation email with a download link. The email states as order status "Paid/Confirmed".
Weird thing is that I received this email now 3 times. Same content.
It has a download link - which doesn't work, because the website isn't. Loading properly....but I guess I have to wait for the servers to calm down.....
