Probably means the person with the file either is not online at same time, else, all their upload slots are busy. So what to do ... try to find more sources. Re-search the file again. After the search has finished, see if the file you are downloading is listed with a Open folder & green arrow icon (see image below to see what I mean; 2nd icon in image), IF it is listed there with that icon it means you have found it. Now if your download does not continue, then select it from the download window & cancel/stop it. Then select from Search results window & press download button. This often restarts the download. If this does not work or else, you didn't find it in your initial search, then right-click (mac users Control-click) the search tab at the top & choose Search More & select Get More Results. Do that every 20 mins or so. You may find someone else who has the identical file. If all this doesn't work, then perhaps the person with the file simply is not online & you may need to be patient & try again each day. Perhaps that person only uses LW periodically such as on weekends.
