{edit}Update - Please see below for a newer version.

Thanks to all for your input. Well... being as I'm as lazy as I am...
too lazy to try and reverse engineer the scripts submitted...

I decided to write my own. It will run on the NAV Parent server as a Task Scheduler job. If anyone wants to adopt it, the first three vars need be set.
$TempDir is where the downloaded file gets extracted to. The script will delete everything in $TempDir once done.
$WorkDir is where the script runs from, creates FTP scripts to, downloads vpcur.lst and symcdefsx86.exe which all but the KiX script get deleted and recreated.
$VPHome is where NAV is installed to on the Parent server. In my case it is C:\Program Files\NAV.

If you want to test it, just create test folders to match and copy your VDB files to $VPHome.
