This is a Java Web Start file. If you are reading this text,
it most likely means that you have not installed Java, which
you will need to play Haven and Hearth. The easiest way to get
Java is probably to go to http://www.java.com/ and download
it.

It might also mean that you are just curious, in which case I
bid you to go ahead. 'Tis a good thing.

Problem fixed in Control panel - Java - Network Settings(Direct...) , then running the Internet Explorer , click in pop up window Connect.
This problem happens when network settings of your PC is changed(new DSL modem, new wifi , etc...)
