You click play on the website, Download the .jnlp file and then right click it and then click "Open With" Then click on more programs, Then do the following
Programs->java-Jre->Bin->Javaws
The Jre file will have some numbers and letters indicating version number, Just click whatever version you have.
This should open the Haven.jnlp with Java web start, If it does not then I would reccomend getting the HnH ender client because that should update and open automatically every time you click on the launch button from the file you saved it in.
