Sociable no icon

Sociable 4.2.6 + WP 3.3.1
The icons don’t show up. http://www.bestweightlossactions.com
The icons initially showed up. After I deactivate and reactivate the sociable plugin, the icons don’t show up anymore. I tried to delete the plugin and re-install it, but still no success.

Searched the forum and tried some of the old tricks without success. Appreciated if anybody know what to do?
