I am totally confused

I downloaded limewire basic (to try it) and for about three weeks it worked perfectly then one day I went on and it informed me I was sharing over 3000 files. It wouldn't let me stop it from sharing the files and the only way I could stop it was by removing limewire from my computer, but I really want it back and I tried to download it again and the same thing happened. Can anyone suggest a way of preventing this from happening again as I really want limewire back.
Thank you
