JME Applet Builder Not Working

I have tried the applet builder, and the code will not load my applet. I added in the tag and it loaded the code though. When I open run-applet.html it loads the loading bar then just freezes. Also, I can’t seem to embed the jme section into my applet. As soon as I click the button to load it, the game freezes with a blank background.

Enable the java console in your browser and read the error output.
