Hi! I'm currently using Vista and have downloaded and installed NetBeans IDE 6.1 on it. But there's a problem occur when I'm working on the project, there's no debug option.. and when I found the option.. this error occur:

All I'm testing for is just this simple code...
Java Code: 
public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
        int a = 20;
        int b = a;
        
        System.out.println("Hello World! "+b);
    }

}
and there's no toggle breakpoint for debugging.. I can only see the debugging option the menu <Run>

Java Code: 
Listening failed with arguments: {timeout=timeout=, port=port=, localAddress=localAddress=}

Can anyone help? I've already tried to check with Firewall, and that's not the cause. I'm running netbeans in administrator mode even though I'm already in the admin and it doesn't run as well.

Thanks!
