Plugin is generating fatal error

I just downloaded the video xml sitemap generator and it generated the following error when I tried to activate it:
Fatal error: Cannot redeclare video_sitemap_generate_page() (previously declared in /home/bnmnewpr/public_html/rastawearcollection.com/wp-content/plugins/xml-sitemaps-for-videos/video-sitemap.php:14) in /home/bnmnewpr/public_html/rastawearcollection.com/wp-content/plugins/video-xml-sitemap-generator/video-sitemap.php on line 39
