so i was having fun downloading music. now every song i try, including ones i've previously downloaded, it gives that warning "limewire is unable to find the licence for this file. download anyway?" I've checked the posts and found many people asking about this message. i did change some of the settings in "tools, options".

does anyone know what i may have done to cause this warning when it wasn't there before? i agree i shouldn't download songs without a licence. i don't want to do anything illegal.

on another note (sorry, this probably should've been in another post), how do i protect my computer files so they are not all accessible to outsiders? i want to do my sharing part, but don't want to get extra headaches for doing something stupid.

thanks for your help in this matter.
