First, you should use the search function on the forum
Awaiting sources means that no source is currently known to download the file.
To fix that, you'll have to find sources for LW: this has been done because there has been much abuse in the past and it made the network much slower. Try to make the most specific search to find your exact file in the search results. When the same file is retrived from results, LW will resume the download.
