You need to find the location(s) of the actual files, which may or may not be in with Jukebox (I don't know how Jukebox works). Go to Limewire >tools>options>sharing>shared folders>add folder and browse for the folders, and add them. You can also do this by adding them in the Library, but I prefer the first method. If you choose to stop sharing ..ON NO ACCOUNT delete them from the library, you should select "remove from share" or you will loose the files off your computer (unless you are using LW4.13 Beta)
As for the firewall question .. Look at this first.
