Please HELP!! Watch worked fine until yesterday's ocean swim. Now it shows the clock and time still ticking along but it won't charge, it won't let me navigate to any other screen and it won't connect to the computer to download. I am doing an Olympic Triathlon in NINE DAYS time!!!!! Please help me - it won't allow me to press the down button to reset or anything. I am really disappointed that this has happened so close to my big event and I can't afford to buy another device in time.
