@tuxic: towo is right, you are not the absolute beginner with no knowledge about linux. And some times it is better to sit back and try some new ways to solve a problem.
My last attempt to help:
apt-get update
apt-get purge sidcution-settings-xfce
apt-get purge wbar*
apt-get install siduction-settings-xfce
apt-get install wbar-siduction-config
Please be so kind and pastebin errors that eventually comes around, the forum is not the best idea for longer pastes.
