I posted a detailed fix for this problem in another thread. THe problem is this: Limewire cannot connect to the Gnutella network if it doesn't know any Limewire peers. The peers in standard release of Limewire are not active. They might be, but it didnt work for me.

The developers changed the location of the gnutella.net file in the latest limewire versions. In the 4.9.31 version, there is NO .limewire directory.

To fix older versions of limewire, go to the .limewire directory and add some peers in the gnutella.net file. Fine my other post and you will see a list of about 35 webcahes that will get you connected.

A help would be to know where the .limewire directory is in the releases.
