Can't download Halo 2 trailer from GFWL

Went here thinking maybe I can buy H2 Vista (of course it’s not available at all).

Figured I’d at least grab the trailer since that’s apparently as close as I’m getting to playing the game.

It says it’s free, so I clicked “Buy for PC” (haha, wut, I thought it’s free)…

“Sorry, this offer is not valid in your region.”

OK, if I can’t download it, why even show it to me and give me a “Buy for PC” button?

I have no clue how that stuff works, but you could probably just go on Ebay or Amazon and pick up a copy.
