[gnome] I can't recover rhythmbox controls

view story

http://ubuntuforums.org – Hi, I have removed various rhythmbox directorys as superuser to make rhythmbox detect my artbox correctly, but what I have done is not fix the problem but spoil the menu bars of the interface (window menu, play/pause/forward/next controls) I remember one of the directorys was /usr/share/rhythmbox How can I recover rhythmbox? I have tried with apt-get remove --purge rhythmbox But nothing works, when I reinstall the software I dont have the controls Any help will be very appreciated P.D: Sorry for my english, I'm from Spain and not bilingual (Hardware)
