I'm going to try to explain this to my best knowledge. MSN has two video features(a new one!): 1) Video Conference(old one, still in version 7.0.0777, just hidden) 2) Video Conversation(new one, only in version 7.0.0732 and 7.0.0777) Your getting an error because you clicking on video conversation. Read on. To use video conference: Open the contact window of the person you want to start video conference with and go to: Actions>Audio/Video>More>Start a Video Conference Not the main window, its hidden in everyone's contact window. It's simple as that. Now about 'video conversation' feature: Microsoft/MSN went with logitech and some other company and created the new feature 'video conversation'(with full screen view). They created 'video conversation' to have the audio/video sync together, instead of having it split up. Makes it better. This feature is not working for me etheir and I think its not working because it hasnt been started yet. Hope This helped.
