fatal error trying to re-activate Email Subscribers

When I tried to update the plugin, it registered a fatal error, so I deactivated it in Recovery mode. When I left recovery mode and tried to reactivate it, it gave me this error:
Warning: require_once(/www/wp-content/plugins/email-subscribers/lite/includes/libraries/action-scheduler/action-scheduler.php): failed to open stream: No such file or directory in /www/wp-content/plugins/email-subscribers/lite/includes/class-email-subscribers.php on line 1143 Fatal error: require_once(): Failed opening required ‘/www/wp-content/plugins/email-subscribers/lite/includes/libraries/action-scheduler/action-scheduler.php’ (include_path=’.:/usr/share/php’) in /www/wp-content/plugins/email-subscribers/lite/includes/class-email-subscribers.php on line 1143

I have zero technical expertise, so you will have to talk to me like I am a five year old.
