cannot move to library

When I download songs it says it cannot move to library. I saw to try and download them to another file, so I tried that. Worked sometimes, and then would say cann't move to lib. again. Sometimes when I started it it also says I have an invalid save directory. I re-start it, it might say that it might not. Basically usually I get one song downloaded, and then it starts saying can not move. Any idea what's causing this.

Nope, but if it occasionally says that you have an invalid save directory, then you might wanna check it out. Go to the Preferences and under Saving or Sharing (I forget) you'll find where your dlds would be stored. Now, go to that location in the Finder and check if the folder does indeed exist or something.
You can also create a new Shared and specify that as the new saving location for LW's dlds.
