where did it go

everything was ok then i attempted to open limwire again and it seemed to set it up all over again. When it opened all of my other lists were gone but were still on my computer. it also showed me not sharing any files. as i downloaded a few more songs and went to add them to my playlist and they did not get added to my other lists on my computer which are in the limewire folder under program files..how do I make it so I can retrieve them from that folder and where are they. and what cause my limewire to basically start over.

something similiar to that is happening to me, when ever i am using it at random times it just decides to exit out and i have to open it up again.
