Hi. Many folks are having the same problem. It appears they hosed something up in the latest version. I had the same problems. I even went so far as to completely disable my firewall and change all my port setting in LW. No help. This version is just plain broken. The good news is Shareaza still works, using the exact same ports. The problem is not the firewall or port setting, it's Limewire itself. Download Shareaza and use it until the problem is fixed.
