Problem with Share Files

I am using a computer with Windows Vista. Limewire 4:16:7. Everything was working fine till 3 days ago. When I started my computer, Limewire started automatically which it is not suppose to do. It gave an error message that my saved file did not exist and to chose the folder I wanted to use. Once I did that it proceeded to show the total of my share files. That number is 27,171.
I do not have these files on my computer. They list things that I have never downloaded. I uninstalled Limewire and reinstalled. The problem still existed.
Any help on this. Because of this I cannot shut Limewire down, and every time I do it automatically starts up and goes threw the same procedure. It is slowing down the overall performance of my system. I don't know if this makes a difference but it is Limewire Pro. Any help would be greatly appreciated as I enjoy using Limewire.
