OK!! drew.
Where did you download your Limewire from, ? If its a cracked version, Bin it.
& scan your system
Use this link & choose the top one jre-6-windows-i586.exe IF that fails, Try the bottom one jre-6-windows-amd64.exe
Archive: Download Java Platform Standard Edition (Java SE) 6
& make sure you have uninstalled all java versions before installing New.
Peace.
