This is the exact problem i have too...HELP. I have download many songs from limewre and even liked enough t o buy pro (although i have not seen any difference yet, but this no connection problem. i turned off all firewall and scanner..still no sucess..reloaded it..no success. Losing it now.

I think its a problem in the actual LimeWire software, just my opinion though. I did a system restore and made it exactly the way it was before I upgraded to the newer version and it still doesnt work.

I have been using Limewire Version 4.12 for sometime and i recently reformatted my computer and now it won't connect. I've tried everything you suggested without any luck. I have tried to search for .limewire with hidden files checked and it doesn't exist. I've looked for it under documents and settings ect.. and it aint there. I uninstalled and reinstalled without luck. I'm using a fresh XP SP2 with all the Windows Updates. Maybe a new update is interfering? I don't have a Firewall besides the XP one and I disabled that but I still have a wall in front of my globe and under bugreport it is saying false. I'm puzzled.

Well I found this and it worked for me.

1.get file gnutella.zip from here (right click - save target as )

http://minasbeis.tripod.com/gnutella.zip

and unzip it

2.go to directory
C:\Documents And Settings\username\Application Data\LimeWire
(where username is the name you use to login to your PC) and replace the existing file gnutela.net with that

3.restart limewire.

It's AWESOME that you posted this and now my PRO version of limewire works fine(TURBO CHARGED CONNECTION EVEN).... Took me 1/2 an hour to find your post....It is VERY SAD that MY PAID FOR PRO VERSION of lime wire would not work without this fileupdate...AND that Limewire does not have an auto fix for this OBVIOUS program bug ......
Kudos ADDAM

This REALLY Worked all you have to do is update it my pro works perfect now no problems any more THANKS!!!!
