Have you tried the different options here Fixes for Limewire (click on blue link) parts 1-5? When we suggest reinstalling Java, we mean remove all previous versions before reinstalling. I would actually recommend going back to Java 1.5; Archive: Download Java 2 Platform Standard Edition (J2SE) 5.0 Update 11 & installing the JRE "Offline" version which means installing from your computer .. not over the internet.
