Hello, I'm using the latest beta of Bookport. And here's the problem: All of a sudden, a few days ago, Bookport started acting very strange. It would stop plaing in the middle of an Audible File. When trying to move between files, Bookport would not recognize the file as being anything. The file was renamed to a null value automatically. Taking the CF card to the computer and performing chkdsk resulted in it reporting file corruption. I performed chkdsk to have the corruptions fixed. I never recovered the original files that I was playing and had to use Bookport Transfer to reload the files. The same process occurred once again yesterday. Then, all of a sudden, I find that the Bookport is not responding at all. I receive a message when I put in fresh batteriesregarding the version and that the bookport is ready. However none of the keys are responding. The batteries are fully charged. Not even a newly-formatted CF card makes a difference. When plugged into Windows, the OS refuses to recognize the device, informing me: "USB device not recognized: One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message." The next thing I was going to do was to reload 2.1 firmware to make sure that this firmware wasn't causing the problem. Before I could do that, however, Bookport refuses to be recognized. I hope someone can shed some light on it.
