Register both Ship Simulator 2008 and New Horizons, and update them to 1.4.2 with the 1.x-1.4.2 update, and go to Shipyard, scroll down past the Super Packs and you will find Jumbo Javelin, click the click here to download to go to the download area, then when you get that stuff done in the area, head to your profile, scroll down to the orange box, and you will have your personal Jumbo Javelin key, highlight it, copy and past it into register key, and click one of the VSTEP Server Downloads to download JJ, and when you do that, write down your key (only if you play SS08 fullscreen), then click Ship Simulator 2008's icon to play the game and it will take you to a screen with Ship Simulator 2008 in the back of the blue screen, type JJ's key (in case it also needs your SS08 and NH keys, you could have wrote them down in case) into the spots it is to be in, then hit okay, and it will take to to the Main Menu of Ship Simulator 2008.
Hope you got that all down
