Now that the "horse is out of the barn" so to speak I'm not sure you can retrieve the files you lost. The only suggestion I have is to check in the folder you designated to save your files. You would have had to designate where you wanted your files stored when you initially setup Limewire. This would be a Windows file.

In the future, you may want to consider copying, at least your music files, to iTunes or some other program like it. That way you'll have a backup copy to go to just in case.
