It seemed to be ok for me but then I tried again and got an internal server error on their site. I'll try again later but if the service has changed it may be necessary to find a new one.
I tried to use VPN and it would not load at all. I did pay $19 to get the key and that is working fine. Seems they changed something.
I theory, we could update the incorders.php to use parameters that utilize our own keys. Maybe we can add this as an option to store admin or includes.php.
