And what is it you don't understand....?
I think your problem might be Java issue, so the best thing to do is to uninstall Limewire (to uninstall lW go START>Programs>Limewire>Uninstall) and all Java from your computer (for uninstalling Java go START>Control Panel>Remove Programs).The reboot your computer. Then download the latest Java version for your Operation System (i.e. Windows XP) choosing the JRE offline installer. Install this Java, restart your computer and then reinstall Limewire,.....simple like this...
