 * When I purchased the Pro version, I uploaded the plugin from the checkout page
   onto my site. I went to activate it and it gives me the following error:
 * Plugin could not be activated because it triggered a fatal error.
    Fatal error:
   Cannot redeclare wp_video_popup_shortcode() (previously declared in /home2/thesimpl/
   public_html/middlemanlifestyle.com/wp-content/plugins/responsive-youtube-vimeo-
   popup/responsive-youtube-vimeo-popup.php:63) in /home2/thesimpl/public_html/middlemanlifestyle.
   com/wp-content/plugins/wp-video-popup-pro/wp-video-popup-pro.php on line 116

 * Please help!!!!
 * UPDATE: This was fixed simply by deleting the free version plugin prior to activating
   the PRO version!
