Hello!

It is pretty hard not to get any uploads these days on Gnutella.Since you are able to get downloads other people must be connected to you and that means that they are able to perform uploads from you.You probably just have this option checked:
Check LW preferences:

Tools>Options>Uploads>Basic>auto-clear completed uploads.

Make sure that that option is unchecked and all your uploads will be saved and you can then check which files that are and have been uploading/uploaded from you.
