Most likely, after your payment, the information has not been updated in the plugin yet.
Go to the plugin settings in your admin page: WordPress Admin Page —> Settings —> Security by CleanTalk. Click the button “Synchronize with Cloud” on the top of the settings page, wait until the rotating icon disappears, and refresh the page.
Also make sure that you enter the Access key for Security and not the Anti-Spam.
