Problem after latest update

After the last update, when I create a new article on my website and click on Publish, appears this error: Warning: require_once(/web/htdocs/www.raplove.it/home/wp-content/plugins/wp-crowdfunding/addons/email/classes/class-wc-new-user-email.php): failed to open stream: No such file or directory in /web/htdocs/www.raplove.it/home/wp-content/plugins/wp-crowdfunding/addons/email/email.php on line 53
