I do not think it has anything to do with Verizon. It runs perfect on my desktop which is on the same home network. Desktop is XP and laptop is Vista. Laptop was running great until I did the upgrade. Did upgrade on desktop with no issues.
I have done as suggested from deleting Limewire completely to getting files removed.
Laptop has 160gb hard drive
2gb ram
Now running Limewire 4.12 thought going back may help
Java is 1.6 again went back to see if it would help.
Firewall is set to exception for Limewire.
I have made no changes to my system. I even did a restore and that did nothing.
Can't figure out why it worked on four days ago and now nothing.
Any help would be great!!!

I have found a fix that worked for me

Can't Connect? Try Gnutella.net file here - LimeWire Forums

That's identical to what's listed here If LW Will Not Connect (click on the blue link). Which is what users here with connection problems should look at first before posting about their problem.

I just wanted to share my experience. Before I realized Limewire wouldn't connect, I also couldn't establish FTP connection to anything from home (Uverse router). From reading posts and faqs, indications were firewall (software or router). Long story short - I had installed a VPN Client software for work a month or two before. I had exited/shutdown this from system tray during troubleshooting, so didn't suspect it further. Turns out, shutting down from system tray wasn't enough - the software had a security policy that apparently was still active. Once I discovered this, I just had to right-click, "disable security policy", and my connections worked.
So lessons learned - 1) you may have a "firewall" coming from somewhere unexpected. And 2) shutting down is not always shutting down.
Very frustrating.
