A download manager might do better at checking for missing/incorrect pieces than a normal download would, I use Firefox a lot, and DownThemAll has helped me a lot at times. It's entirely a plugin for Firefox, no separate install or such.
I used to know of several nice free download managers but I haven't had to look into any others in a long time.
