I don't know that you can, unless you go through a proxy page. I know when the new DR who game came out in the UK, I couldn't order it here in the states, so I went through a proxy , Bought the game, and was able to download it.
Now if MD has proxies blocked, then I have no idea.

PS. Be careful using those P2P places. they are really shifty, installing crap on your pc. That being said, some games like WOW or D3 you almost have to go through their P2P in order to download it at a reasonable rate.
