"Limewire Document"
 

I downloaded a program on Limewire (******). It was a .zip file but when I looked up the file information it said that it was a Limewire Document. Everytime I double clicked on it, it would open Limewire. I can't change the type of document it is and I can't make anything happen within the Limewire program. I don't understand what I'm supposed to do. I can't even unzip the file! Does anyone have any idea what I'm supposed to do?
