Thanks for the advice. I have been tearing my hair out to get limewire to launch. It had all been working fine until today. Followed your advice, deleted Java (was an old 1.4 version), deleted limewire, reinstalled Java 1.5 and then limewire, and hey presto, all was ok!

Many thanks for your help. I just wonder why limewire should have required the java update today. Or maybe it was just the reinstallaion that did it. Anyway, it worked for me
