This is not an individual problem. Everybody suffers this same thing. The best thing to do is to delete the file from your dwnld window(below the search pane) & reselect this file to dwnld from your search results. Try this several times if it doesn't work. Then try another search for the file over the netwk to find fresh & possibly new resources. The Gnutella netwk is very large & is connected throughout the world. People are constantly entering & leaving the netwk. This may cause a loss of connection to your file. Also, if you're dwnlding from a T1 for example, their netwk may have temporarily blocked you out. The source you were dwnlding from might be busy with other uplds also & your connection was knocked out by others attempting to connect or trying to gain a greater upld bandwidth from your source. When you go onto the busy list, it means just that, that the sources are busy & you have been put into a cue to share dwnld time with others (yes after a time you may be forced back into a cue again as those others in the same cue are rotated. There's numerous reasons why this happens & these are just a few. Hopefully & with a bit of luck you can reconnect by taking my advice or even maybe finding a new source. Good Luck.
