Work or don't work???

Hello.
I have installed transposh on http://www.madeinitalya.com and i have run the translation of entire site.
if i check the sitemap (http://www.madeinitalya.com/sitemap.xml) i can see that all post have been translated from italian to english.
But if open one of this post i can’t have the english version.
also if i click on ENGLISH in the widget or if i connetct with usa or uk ip.
Wich is the problem?

francesco
