If you try that and it doesn't fix the issue, could you enable the Java console and post the output from there when you try and run the viewer? Instructions on how to do this can be found here;

Also it's worth making sure your Java is up to date. Are you trying to connect through a proxy server, from a work or uni network maybe?
