When I try to download a song it usually is incomplete (doesn't finish downloading). I would like to smart download but I see no option for doing this. Is smart downloading automatic for any download? Clicking the button to force the download to continue fails. Once I quit LimeWire, my incomplete download seems doomed to stay that way.

How can I resume a download? How can I get a completed download?

LimeWire 1.6d on Macintosh B & W G3.
