I'd like to remind everyone that the right place to ask KPilot questions is in a forum that actually gets read by KPilot developers and users -- that forum is the mailing list
kdepim-users@kde.org. While you're at it you might report that your device works with KPilot, to keep the device compatibility list up-to-date.
Please provide details of what is not working or what kind of error message you get. Remember that the file installer can only install .pdb and .prc files, nothing else.
