How many editions were there?
I know there's Gamestop and Best Buy special maps.
GameStop Maps
Best Buy Maps
But the map you mention is not included in any of those...
Anyways, I had the Gamestop one, so I went to activate it, noticed the link, remembered that there's a best buy version too, replaced 'gamestop' with 'bestbuy' in the link and voila, it worked.
