Do not touch the files in the incomplete folder itself. Go to Limewire>library>incompletes. Select the files you want to resume and click resume. They will search for sourses in the download pane.
Often it helps to re-search the keywords in the file and this can kick start the file into restarting, as Limewire does not always find the file on its own.
If you see a serch result with what looks like a torn paper icon. This is a file you have incomplete. Downloading that file from the search windo will restart your incomplete file.
If none of this works, re-search the file and start from scratch.
I hope this helps
