doesn't work at all

I used to have this plugin on another website that I quit some time ago. Everything worked fine.
Now I installed this version on a new page and it doesn’t work at all. There’s only a foreign language available which I can’t recognize, it’s all about “FUente” or something like that although I wanted to install the classic sociable, the settings are nowhere to be found and it totally messes with the wordpress menu on the left.
