Google Map not working

Uncaught ReferenceError: loadGMap is not defined

I try to refresh the page "contatti", but nothing appears into "div id='map_canvas'".

Please help.

[solved]
I've tried to reinstall the Sport theme via FTP instead of uploading the .zip file into wordpress dashboard.. and now it work!

Again, the problem is not solved.
when I install the theme anything is working, but when I active it with the activation-key the links in the footer get removed and the Google Map is no longer diplayed!
How can I resolve this?
