Primo: only dld Limewire through the official site. That is
www.limewire.com. The rest are scammers and if you dlded it after getting some kind of membership (like, for 2 years), then you can be sure that you were scammed.
Secundo: Dld the latest Java from
www.java.com .
Dld Limewire from the official site.
Install Java.
Install Limewire.
That's it: the installers provided by the official sites will work (most probably). If they don't, they probably got corrupt during the dld. Either redld them or post back here.
