I have a 30 gigabyte ipod that I use with the musicmatch jukebox software on my windows xp machine. Lately I have wanted to delete some songs. I go into the MMJ portable device manager just like normal. However, when I scroll through my list of songs I find that some of the ones I'm looking for are missing. I can see them on the list on my iPod, and they can be played, but for some reason MMJ doesn't realize they exist. Has anyone else had this problem? Any help would be appreciated.

Thanks.
