I recently perfomed a hotsync with my centro and my laptop (WIN XP).  During the hotsync threesome of my categories (contacts) were deleted.  I am not trusty why.  I hit performed a hotsync before and the categories were not deleted.  My surmisal is that I inadvertantly denaturized whatever environment or something. Can someone provide me whatever brainwave or direction.  I am fascinated in lettered the ground as substantially as how to better the categories. Thanks in advance.
