Are you saying that the emplode UI refuses to allow you to move them around, or that once you sync, the empeg doesn't reflect how they appeared in emplode?

If it's the latter (and this is just a guess), it might be that you reordered them visually, but the playlist order wasn't changed. There should be a column that shows that order (I forget what it's called, but it should be the only numeric column that's not track number). It might be that while the tracks are in the correct order visually that those numbers aren't sequential. To fix this, once you've got them in the right order, press the toolbar button that looks like a double-headed arrow with an `A' and a `Z'. That should rectify the playlist order to what's being shown.

If it's the former, I've got no idea. Try using the up and down arrow toolbar buttons to move the tracks, maybe.
