hello lord of the rings,

pls i'm using the latest limwirepro 5.3.6 ,...i had about 4 video downloads which were all over 50%,..but after a while after i shut down my computer and restart,..all the video downloads were stalled,...but when i click on fix stalled ,..it attemts to restart but after this it returns back to stalled position and tells me to search for video again,.....after i search for one of the video again and try to redownload,..nothing happens untill i delete the video,..but the download started all over again from the begining,....i still have the other 3 remaianing downloads stalled but i dont want to lose them because they are large files.,.restarting them will take too long to downlaod again,..pls what can i do to make stalled files continue or resume download as pressing the FIX STALLED does not work.....i dont want to lose the video files because they are already over 50%,...........THANK YOU
