I'm also having this problem during the live update. Mine is US account. Can reach the content inside the MarketPlace but cannot download some of them especially new purchase Gow map. So stick playin old map. Btw no prob wif MS points.

Eventually after 1 week i tried again and then...............can download But untill 2day, still didnt play it yet Forza time

its happened when im done wif the update thingy. Cannot download and error msg 'ur download content is not available at ur current location'. Somewhat like that la.

So i tried wif clearing the marketplace data memory but still no go. Only after a week i manage to dl again. yeah.......weird. But many says that SG acct no prob but still sume of them facing this problem too. i think the update screw it.
