the problem is with the automatic java updates(i believe); go to my computer and open program files then double click on "executable jar file"
oh yes open limewire first.
limewire should now open-then you will see a security alert "java tm platform se binary" 'do you want to keep blocking ...and so on click on unblock!!!!! my email addy has changed by the way; i'll try to edit it. thanks revenoor.
