Most of us here give it away for free. (and of course no income from this); Except for the site owner /admin.crash'd site
We do it for free for the community.
So you want more detailed help: please report the error details so that others can help you easily.
I don't even use this Plugin, I have to install a separate wordpress website to check it / and other plugins.
For WordPres site: You should install plugin " query-monitor " and edit /add line " define( 'WP_DEBUG', true ); " at /wp-config.php. It will help show you the error details.
I'm so sorry for what you've encountered.
Take a screenshot and post it here.
