The file doesn't show as password protected for me

Anyway, try this new link (it's definitely not password protected):
gnutella.net
The zshare link works fine for me. But - here's another of those as well:
zSHARE - gnutella.net
A few other people have said that they didn't even have a gnutella.net file to start with! That's ok - just put one into the LimeWire folder (make sure that LW's properly closed first)
