Partly this depends on which OS and platform you use, but why don't you go to
www.limewire.com and download Limewire 4.10.9 Basic and see how you get on. You've nothing to loose. I don't remember 4.9.7 being particulary notable, and if you downloaded it on p2p you might well get a dodgy copy.
4.10 uses a junk filter which is now OK .. and if you go to
