Google "Net Transport" probably the best free download manager. I downloaded Vicky 3 using dialup without a DL manager since CL discourages you from using one and the first download was corrupted had to do it again. I've downloaded 150 MB size files using Net Transport or Flashget without a problem other than it taking many hours. If you don't have a CD/DVD burner or an external disk, save a copy on another physical HD if available or at least on another partition.
