I tried to add it many times, and then I tried another folder, but I figured it out. I couldn't go to the folder and just add it. I had to click on the limewire folder and then type in shared under the file section on the lower part. Then when I pushed select, it added it to the sharing section.
I know this is hard to make sense of, but the good news is that it now works.
Thank you for your help!!
