that is your permalinks. go to admin turn off permalinks and view the site, you will then see that the menu is functional.

your .htaccess file needs to be edited, and you need to set this line:
php_flag register_globals Off

php_flag register_globals <----- Set this to off.

now your menu links are working, but they are not search engine friendly, now you can go back to admin and re-tick the permalinks box and all should be well.
