Salut, do a search on all your hd for limewire and thrash all what in the folder preferences. Dl LW 3.6.6 from the website and reinstall it. (note that an osx install over a previous intallation in BAD, the best option when installing is to archive and install -it keeps all your documents and such-) for more help installing osx go to http://macbidouille.com/article.php?id=137 the best mac site out there.

Bonne chance, LW works great in my 10.3.
