Limewire Trash bin? or lost files?

[Koto]

I have had aa major break dwn of my comp and just yesterday completed downloading 400 songs onto Limewire. There was this one song that I didnt really like anymore...so I right clicked on it and selected delete...when I did that...my whole library was deleted. All 400 songs. What I want to know is this: Is there a trash can where I can go and retrieve all my songs....or is there something I can do to get them back. Another thing...I selected them all and pressed the Enqueue button and saved all of the songs on a playlist. I have that playlist saved but is it possible to upload it again. Everytime I press the upload the playlist does nothing....and how would I get the playlist back up into the library?
