Sorry to hear you are having issues. If you're looking for saved sound package. You can browse it by click "Browse to my saved sound packs" button.
On the Soundpackager don't load on startup. No, soundpackager don't need to run all the time. I believe when you apply a soundpack. It will change the Windows sound theme to those that come with that soundpack. The sound should stick as long as Windows don't change it back to its default theme.
With that said, what is the issue on your system? If you apply those package that come along with SoundPackager, does it work?
