Here's what I do to maximize downloads when this happens.

Try right clicking on your download and goto search. Another box will appear with two choices. Pick the search choice that matches your download and LW will search for more files that match yours and give you more hosts to download from.
It will do this automatic so if you are awaiting sources or whatever it should automatically start redownloading and with multiple hosts. That is if it finds more files of the one you are downloading.

GoodLuck!!!!
