Awaiting sources means you've already attempted to use the Resume function on it but it can't find the sources to downld from. Why not re-search the topic to see if it will start. If it's in the search results (will have an open manilla folder icon next to it) then you can stop it from the downld window & reselect it from the search results. If this doesn't work then perhaps you should try one from the search results with many more sources under the # column & 3 or 4 stars which represents your chances of connection & successful downld.
