87% done and speed drops to 0
 

Hi ive just downloaded a torrent file and when it got to 87% the speed dropped to 0 but it still says im downloading from 12 people.Could this be a corrupt file or is there something i can do to sought the problem out??

my isp is aol
windows xp
router

ive been using limewire pretty much trouble free for about five years so i dont think its a problem of my computer but im no pro so any help would be great.

many thanks

matt
