I shouldn't make suggestions before you get back but ... if you're still having problems after defragging & a system checkover, then try another version of Java or LW. Uninstall Java 1.5 & instead use Java version 1.4.x Sometimes Java 1.5 doesn't behave very well on some people's systems. If that still doesn't work then I'd suggest the beta 4.3.4 which is not so different to LW 4.4 but it has solved a few people's problems: http://www.limewire.com/english/content/beta.shtml
