Warning message

I am a newbie. I have this message appended to my blog page and to the admin page:
Warning: include_once(/home/xxxxx/myplaceinjerusalem.com/wordpress/wp-content/plugins/myvigilance_PRO/) [function.include-once]: failed to open stream: Success in /home/sharonmechi/myplaceinjerusalem.com/wordpress/wp-settings.php on line 473

Warning: include_once() [function.include]: Failed opening ‘/home/xxxxx/myplaceinjerusalem.com/wordpress/wp-content/plugins/myvigilance_PRO/’ for inclusion (include_path=’.:/usr/local/php5/lib/php:/usr/local/lib/php’) in /home/sharonmechi/myplaceinjerusalem.com/wordpress/wp-settings.php on line 473

I have no clue how to handle this.

Thanks
