You posted here apparently with no real desire to troubleshoot your problem
. In the previous thread and this thread you never answer any of davidfor's questions. For the record this is not a calibre problem since it is unique to your machine and reader. I also believe if you wanted to correct this issue, that by providing the information requested we could have helped you solve your unique problem.
