Hiya,
Open the Disc case (DVD Case), there is a sticker in there. (On my one it's on the left side inner casing.)
This sticker has the New Horizons addon license key code and the Ship Simulator 2008 license key code.
If a sticker doesn't exist and you bought it from the official ship simulator website (
www.shipsim.com) you can contact VSTEP or a administrator here.
Once you've registered your Ship Simulator 2008 license key you can get the Jumbo Javelin, this you download in the license key section on your profile.
One way in finding out if you've registered your Ship Simulator license key is by looking at your posts - if you have 5 icons underneath your username then it's done (just like mine <<) - if not try again.
