General :: Import All My Music - Rythmbox Won't Remember Once Close ?

I am trying to use Rythmbox to replace windows media player, in Ubuntu 10.04. So of course, I needed to import all my music. So in Rythmbox I go to Music>Import Folder and then I simply select the correct folder, which is on a different drive. And sometimes, that works. even though it won't remember that I did it once I close Rythmbox. Other times, when I do that, Rythmbox simply closes right then and there, and has to be reopened. I don't really know what is going on here, other than what I would call a bug. But it never actually keeps the music file that I imported. I always have to re-import it, every time I open Rythmbox.
