I see. The way this works, and it's the same for most online purchases is:
You buy the game online, either for download, or a 'shipped' boxed version, but the payment is through an online transaction from your Credit/Debit card. Most online retailers don't send anything for 'payment on delivery'.
The only suggestions I can make here really are, ask someone with a Credit/Debit card to make the purchase for you, or wait a little longer until it's available in the stores in your Country
Patches/Updates only update your current game/s, they don't allow you to obtain downloads for Add-Ons. The Add-Ons are separate purchases
The latest patches/updates are available, here:
http://www.shipsim.com/downloads/patches.php
It's always a good idea to download the patch with the highest number. Ship Simulator 2006 needs the 1.8 patch, Ship Simulator 2008 needs the 1.3 Patch
