Welcome back.
The LimeWire company has closed to my knowledge, or at least will not be involved with the same application. But remember you were not downloading from a 'site' but other users on the Gnutella network like yourself.
However, you can still use LimeWire. Be it the 5.6.2 pirate edition
http://www.gnutellaforums.com/gettin...e-edition.html or an earlier LW 5 version. Or you can even still use the LW 4 version if you prefer but would need a connection fix.
And of course there's other alternate programs you can use such as Phex. Or BearShare 5 which is the section you have posted in. And GTK-Gnutella or FrostWire 4 or ShareAza.
I've moved this thread to the LW Open Discussion section instead of the BearShare equivalent.
