ubuntu software center no loner opens when selected or ran from a terminal on xubuntu 13.10.

[Istimsak]

Installed ubuntuone-client via terminal. Could not execute ubuntuone-client.
previously ran ubuntu-software-center to install ubuntuone-control-panel-qt. After installation, tried to run ubuntu from the "settings manager" window. Ubuntuone did not execut. Install synaptic-package-manager. Searched for ubuntuone. Found the apps relative to ubuntuone were installed. Tried removing all ubuntuone packages and ran:

#sudo apt-get remove ubuntuone-client #and
#sudo apt-get autoremove

Packages dpkg thought were related to ubuntuone were removed.

Tried to open software-center again, nothing happened. Tried running the program via terminal. Got this error message:
