When you go to the link, it should start automatically. I have been having issues with it when I use Mozzilla Firefox as the browser but it works fine if I use Google Chrome. I tried fixing it so I could use my regular MF browser and the support page says to make sure your flash player and operating system are up to date and see if that helps. I did all that and STILL have issues using MF as my browser with Ustream. Others though don't have any problems.
