Doesn't Work

Perhaps I’m the only oddball in this world that uses this plugin and it doesn’t work for. My operation is simple, videos are being imported via Automatic Youtube Posts Plugin and I have video thumbnails plugin set to “Check this option to automatically set video thumbnails as the featured image (requires saving to media library)” and “Checking this option will download video thumbnails to your server” and “Post” checkbox checked. In over 160 posts so far I have yet to have one thumbnail automatically show up under the “Video Thumbnail” or the “Featured Image” sections of the post. That’s the issue I have with this plugin.
