Multi threading not working on RTX Kernel fro LPC1768

I am trying to configure RTX Kernel for LPC1768.
I use RTX help from "http://www.keil.com/support/man/docs/rlarm/rlarm_ar_create_newapp.htm"

In the help a file named RTX_Config.c is suggested (but it is not there at the suggested place) then I imported RTX_Conf_CM.c. Rest of the steps I have followed.

But still Only one execution thread is running.
here is structure of my code.

__task void CommandHandeler (void);
__task void init(void);
__task void MainThread(void);

__task void init(void)
{
        Print("Check 5.");
        os_tsk_create (MainThread, 2);
        Print("From thread 0");
        os_tsk_create (CommandHandeler, 1);

        while(1)
                os_dly_wait (5);
}

__task void MainThread(void)
{


        while(1)
        {
                delay(10000);
                Print("From thread 1.");
        }
}

__task void CommandHandeler(void)
{
        Action Act;
        while(1)
        {
                delay(20000);
                Print("From thread 2.");
        }

}

int main (void)
{
        SystemInit();
        SystemClockUpdate();
        UARTInit(0, 9600);      /* baud rate setting */
        os_sys_init(init);
}

This is the Output of that coded:
Check 5.
From thread 1.
From thread 1.
From thread 1.
: :

Rest of the print never comes.

Thanks in advance.
