im trying to download a file i really need and its status is always awaiting sources is there any way to make it download faster

If it is awaiting sourses, then no one on the network is currently sharing it. Try re-searching for it a couple of times, or failing that re-starting limewire and re-searching might help.

But in all reality, I should wait a few hours and try again re-searching. It is probable you will find your file eventually, but it will most likely not be the one you have awaiting sourses.
