MSP430 Interrupt Problems

I am new to the MSP430. For some reason I can not get the interrupts to work, they never trigger. The code in the interrupt service routine never runs. Any help that you can offer would be greatly appreciated. I have read around on several forums and have not found similar problems, so it must be something dumb that I am doing. I have included the code below. I am using CCE.

Best regards,
Patrick

#include "msp430x42x0.h"

int main(void)
{
  WDTCTL = WDTPW + WDTHOLD;       // Stop watchdog timer
  P1DIR |= 0x01;                              // Set P1.0 to output direction
  TACTL = MC_2;
  CCR0 = TAR;                                 // Current state of TA counter
  CCR0 += 1000;                              // Some time till first trigger
  CCTL0 = CCIE;                              // enable capture/compare interrupt
 

  for (;;)
  {
    volatile unsigned int i;            // volatile to prevent optimization

    i = 10000;                          // SW Delay
    do i--;
    while (i != 0);
  }
}


#pragma vector=TIMERA0_VECTOR
__interrupt void Timer_A (void)
{
    P1OUT ^= 0x01;
        CCR0 += 10000;
       CCTL0 &= ~CCIFG;
}
