I simply had to post this....woo hoo!!...it worked for me!!

I just replaced the gnutella.net file
and voila...Limewire connected!!! Here's the lowdown:
I had used
Limewire previously (Ver 4.14..) without any problems (Even when I was behind a firewall)...that was about 6 mths ago. Then when I tried using it today....it didn't connect. There was only 1 bar in the connection status
and there was a brick wall in front of the globe. I updated to
Limewire 4.18.3 but still nothing. Updated Jave to
Java 6 update 10 Beta. Still same results. Last, with no options left, I decided to go to
zSHARE - gnutella.net and downloaded the file
and replaced the old one with this one. Well!!! It worked like a charm!!!

I opened
Limewire 4.18.3
and the connection bars started rising...and rising

until they became all green
and guess what? The brick wall just disappeared!!!....Now that's amazin!!!! I have to give a shout out to Birdy
and his excellent tips!!! Thanks mate!! You were a real help!!!
