Error when adding a video

Hello,

I've just migrate my site to Easy Social 1.4.1, and i'm trying the video support.
When I try to add a new video (upload or link) I get a white page, with this error in my error.log :
"PHP Fatal error: require_once(): Failed opening required '/home/sites/xxx/administrator/components/com_easysocial/includes/video/adapters/everyone.php' (include_path='.:/usr/share/pear:/usr/share/php') in /home/sites/xxx/administrator/components/com_easysocial/includes/video/video.php on line 1367, referer: http://www.xxx.fr/index.php/quoi-de-neuf/videos/form"
In this directory (../video/adapters) I have only this files :
"abstract.php event.php group.php user.php".

I have this error even if i change the privacy before submitting the form.

Edit : I've just download the full package : this file (everyone.php) isn't inside.
