Great idea but worthless app

I would love to have this app working since I need it for webinars but its a pain in the neck. Im asked to register even if I already am and Im told "I dont have the app installed". Either sound or image doesnt work. Stops suddenly, cant go back. I switched to the computer, I got tired of this. Please do something.
