Can't you buy a UK direct download if you are not from UK (e.g. from http://game.gamesplanet.com/produit.html;jsessionid=BFA61837C4FF9525FF52304E2A42E081.jvmGpfr?product_id=1437&category_id=25)?
Otherwise try Amazon from whichever country you are in (Amazon.com, Amazon.ca etc).
Bought mine off eBay here in the UK
