I just got my Cybook and I've had to reset the device 5 times in 3 days. The first three times the device became unresponsive after five or more hours of reading (even though I switched it off for a minute a couple of times during this period). The last two resets were done in a span of less than 2 hours. I've tried everything: changed all my files to mobi; got rid of the pre-installed fonts and used one I downloaded; uploaded my content from both mac and pc; and checked to make sure the device was 100% charged. I contacted Bookeen and they told me to reformat the device. I did and followed all the precautions listed earlier. If anything, it's worse since like I mentioned earlier the last 2 resets had to be done in less than two hours. I emailed Bookeen again and have received no response. Could it be that the machine is not made for extended periods of reading? Has anyone else encountered this problem in the lastest batch of Cybooks?
