That happened to me once where the incomplete folder was in my shared folder. Maybe try uninstalling and reinstalling. The incomplete folder should be in your LimeWire folder, but not in your shared folder. You shouldn't delete your incomplete folder as it holds the information from your last session. When you start LimeWire again, if you have a partial download of a file, it will pick up where it left off. If you delete it, you have to start all over again. I hope this helps. As I am a Mac user, I can't give much more information about moving files in Windows. Sorry.
