Not a problem with Vista - it is your PC and its configuration.
This site appears to work OK for everyone else.

 I tried with firefox and netscape browser and they do the same, it is something with Vista.

     My Windows Vista system I cannot access the
     http://halo3.com/believe/test/shell.html website.  It flashes a brief
     message that my Flash player needs to be upgraded and takes me to enter
     birthdate.  I enter my birthdate and it says that I do not meet the minimum
     age requirements and my birthdate turns red.  Yes I was born in '63.  I have
     Flash 9 installed, and the latest java.

     This site works fine on my XP machines.  However they are lo-rez.  And when
     I access this site on my XP machines I get a screen with a mercator world
     map and ask me to select country region then takes me to the enter
     birthdate and get right into the site.  On my Vista system it briefly
     flashes the Flash 9 upgrade
     message then prompts me for my birthdate.  I enter my birthdate, hit submit,
     the date turns red, and says I do not meet the minimum age requirements.

     My Vista machine has an 8800GTS card which I am looking forward to viewing
     the site with this system over my laptop with an old Radeon M300 graphics
     chip.
