I hate to say this, but...

I have never successfully used jEmplode.

Every time I use it it does something odd. I'm going to try to use it more from now on in order to get some good bug reports, but only if I'm not in a hurry, as I inevitably have to copy all the files over to a Windows machine and use emplode from there.

The latest thing that it did to me was that I was trying to upload a new album. I created the artist's playlist, as it was an artist I didn't previously have on the empeg. I clicked the new song directory button and selected the directory that contained the mp3s for the album. Everything looks good after I do this.

When I synchronize, it claimed to fail to upload some of the songs (I apologize -- it's been a few days), but attempted to finish the sync. It got to the point where it was waiting for the player to restart, and it never came back. When I went to use emplode to fix it, it appeared that the songs were never uploaded at all, and no new playlists had been created. It did have to rebuild the database upon initial connect.

This was using jEmplode build 45 under MacOS X, installed using the installer.
