Blocklist fails to apply

Just installed and paid for premium, but unable to install the blocklist - keeps coming up with an “The link you have followed has expired” error message.

PHP 8.1
Most recent WP release, as this is a new install.

Can you open a technical support request via the “Contact Us” submenu please?

That’s the quickest way for me to find all the relevant info about your install.

Thanks!
