If you have chose to not share your songs here is what you to do retrieve them: Tools > Options > Restore Defaults. after that it will pop up a box that says some components may change the next time you open LimeWire. then, exit LimeWire and restart it, it will then take you thru the process as if you have just downloaded it and it will ask you where you want to share your files from. 'okay' on the shared file they give you and all of your files will be back in the Shared Folder in your library.
