Where did you get your LW client from? If you didn't download it from the official LW website http://www.limewire.com/english/content/home.shtml, well, then you might have a faked one, which tries to trick you in leading you to that website; just my 2-cent-worth though.............you might consider to download LW basic from the official website and try it.

By the way, that's the second time I've read this here today.
