I had no problemo at all.
Here are the steps I took:
1) go to
http://www.atlanteitaliano.it 2) Click on "Cartografia" on the top of the page
3) Under the "Accesso Libero" click on "Accesso"
4) When the "OK/Cancel" box appears, click "OK"
5) Click on the "Accetto" box
6) When you see a regional map of Italy on the upper left side of the screen, pick a Regione and navigate your way around.
Of course, you will need the plugin.....
