I would try to uninstall making sure that everything has been removed.
1. Move the Limewire app to the trash
2. Move the pref folder from users/yourusername/preferences
3. Check elsewhere for limewire related files and trash them.
4. Reinstall limewire.

I have had Limewire running on my iMac since i got it in december, and we have got along fine, but I went to opened it the other day the icon bounces a few times then gives me the application limewire quit unexpectedly window. I have tried relaunching, resetting and restarting options all to no avail, I have also reinstalled limewire only to be faced with the same problem. I am running leopard and have kept up to date with all the updates and have now run out of ideas. Please can somebody help??!!!!
