I receive some emails from you. They are exciting challenges designed to help me practice speaking on topics that matter to me. When I click to the button I go to a special training window at my browser and start my exercise. I like the exercises. They worked well in the past but recently I started to experience the problems. The page stop working during the exercise. It happens sometimes during the introduction speech from the system sometimes it stopped working when I speak and other time on system respond to me when I listen the question from the system. I don't know if it's only my computer doesn't work or it's a common problem of the system. Please advise if it's my computer is anything I can do to fix it.
