The numbers are actually line numbers in the source code of where the error occurred ... So the error message is pretty straightforward, but the reasoning behind it could be many different things. Have you ever installed LimeWire directly to see if you can get that to work on its own? When that runs, it will generate a file that contains the list of gnutella hosts that were found (I don't have the source handy to tell you the name of that file). jEmplode expects the same file, but I believe it loads it out of your home directory (Documents and Settings/yourusername on Win2k, I think). If you can track down that file, then just copy it into your home dir and rerun jEmplode and see if it works .... it's supposed to automatically generate that file for you, but obviously there's something wrong.

Basically, if you can't get limewire to work on its own, you won't get Serendipity to work, so that's definitely your first task.
