remove all of the java runtimes then d/l the new runtimes from sun microsystems. here: http://java.sun.com/j2se/1.4/download.html the new runtimes ... specifically with windows XP ... which was released with limited java support ... the Java 2 service release from sun ... linked above ... resolves many issues and speeds up limewire.

uninstall limewire (including directories, and regristry entries) ... d/l a fresh copy ... install fresh copy ... limewire installer will install version 1.3 of java runtimes ... uninstall them before running limewire ... when limewire starts direct it to the new java runtimes located in c:\program files\java\{something}\bin .... its looking for javaw.exe ....

sounds complicated .... its not ... its actually pretty easy.
