not to worry, it is likely this pc problem.

i just found JAVA

Java SE Runtime Environment (JRE)
JRE 6 Update 12
This release includes the highly anticipated 64-bit Java Plug-In (for 64-bit browsers only), Windows Server 2008 support, and performance improvements of Java and JavaFX applications.   Learn more

Java SE Development Kit (JDK)
JDK 6 Update 12
This JDK includes the JRE and command-line development tools that are useful for developing applets and applications.   Learn more

I installed both to be sure, and it works now!

It take a lot of time maybe 5 minutes or there about to load the applet on this PC. but it works so i am not complaining ;D
