Thanks for that, sorry late in replying, I've been away. When I updated to 10.4.2, tried to run limewire, the icon in the toolbar bounced a few times then stopped. It just wouldn't run. I tried running from the programme, nothing. I followed the fix you described, still nothing, updated to the latest version, exactly the same. I've tried to find everything associated with limewire, deleted it, reinstalled but still, the icon bounces a few times then nothing. Any help would be great. Thanks.
