Download in the UK

Hi All, Firstly i'd like to say hello! - Been playing silent hunter since the first one and loving every minute of it! I've been a long time lurker on these forums, so decided it was high time to say hi to you all!

Anyway, onto my question. I've got SHIV, but really miss the whole u-boat feeling. So have decided to get the latest expansion! I'm wanting to pay for and download the game off the internet, but can't find anywhere that'll let me get it (I live in the UK) I found a link in another post to gamesload.de - but it's all in german and I dont understand a word of it!

Does anyone know anywhere that i can purchase and download the game from the UK?

Thanks in advance for your help!

James.
