if you have the free ipad app ("videoscribe anywhere"), you probably need to make an in-app purchase to publish to sho-co or to render a video to your camera roll. apparently it does not publish to facebook or youtube.
if you are using a 7- day free trial of videoscribe on your computer, you can publish to facebook, and youtube, but you cannot render videos to your hard drive or to sho.co
paying users have all of the options.
if that does not answer your question, please describe the problem more clearly and provide the exact error message.
