cannot access the John-117 Monument website

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. On my Vista system it briefly flashes the Flash 9 upgrade
message then prompts me for my birthdate.

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.
