Fatal error

Hi. I’ve installed this awesome plugin on wordpress 3.8.1 and it work so well. Today i’ve installed it on 3.8.3 version and recived this message
“Fatal error: Using $this when not in object context in /var/www/clients/client1/web15/web/wordpress/demo09/wp-content/plugins/advanced-responsive-video-embedder/public/class-advanced-responsive-video-embedder.php on line 323”
So I hope this problem can be solved so soon.
