Hi, that was me, i gave you that link with exporter and directory where it have to be placed.
Strange that you found that folder in Default User\Application Data area, because i runned search on my computer and couldn't find the .blender folder anywhere except where i told you. As you can see it's full of scripts, your folder should look the same as mine.

maybe you're using not instaled version of blender, there is two types of downloading blender: Instaler and Archive. I'm using instaled Blender 2.44 and have instaled python 2.5.
