Delete the posted content of autohaven above ...

You click "play button" - a window appears and ask what to do with autohaven(.jnlp) - choose "Open" with "Java Web Start Launcher" ... this opens the file - gets the information what to download - does it and then launches the game...

You need Java installed properly - you're not sure ?!? - test it:
