Does LW show that your firewall is blocking it(brick wall in front of the globe icon)? If so then that could be the problem. See
Connection problems? Check here first!.
If not then probably no on has tried to upload your files. If you only have 9 files in your shared folder you may not get any hits. As your library grows you will start seeing more uploads.
Go to the library page and look under the uploads column. It looks like this 0 / 0, the first number is the completed uploads and the second is the attemps.
