Hi. I am having similar problems to a recent topic of discussion on this list--book port not being recognized after firmware and software updates were installed. I am using Windows XP service pack two and am wondering if this is causing this problem. When I connect the book port to the usb cable nothing happens. The software does not launch unless I fiddle or jiggle the cable end closest to the book port and then I can get the book port transfer to launch. After I disconnect the book port it some times locks up and no amount of presses of the two and the b keys reset the unit. I had to remove the batteries yesterday in order to get the unit going again. I even pressed the d e and f keys so as not to lose my settings and lost them anyway. Anybody else had this problem?
