I have the sme problem. I think that the file is linked to a specific host and when that person logs off, the download is stopped. It will only start again if you are on line at the same time as the person who you started the download from in the first place. I get results by re-searching and replacing the request with a new host. Of course, a few files I'm looking for are hard to find and the one host I need isn't accepting uploads very often.
