critical error upon registration

Hi, I just purchased an extended license for AIomatic. I installed in a brand new website. Deactivated all other plugins and activated default 24-theme. When going to /wp-admin/admin.php?page=aiomatic_admin_settings it gives me an error message. There has been a critical error on this website. Please check your site admin email inbox for instructions. Learn more about troubleshooting WordPress. Front-end works fine though. Also no errors in my server-log. Please assist. Thank you Wouter
