Just 1 version is bad

I get this error for the latest:

Warning: require_once(/includes/class-admin-wp-mailto-links.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/61/10784661/html/clemmodel/wp-content/plugins/wp-mailto-links/wp-mailto-links.php on line 18

Fatal error: require_once() [function.require]: Failed opening required ‘/includes/class-admin-wp-mailto-links.php’ (include_path=’.:/usr/local/php5_3/lib/php’) in /home/content/61/10784661/html/clemmodel/wp-content/plugins/wp-mailto-links/wp-mailto-links.php on line 18

Every version before works. An update will fix this
