MSP430FR5949 Can not get UART A1 to work, A0 works fine

I am having a bit of a confusing issue. I got my UART A0 to work just fine (Thanks Akash!). However when I try to enable the second UART (A1), nothing works, even with the same settings! (Except of course, the P2SEL bits). A1 also will not work on its own, with the same settings as A0. How do I get A2 to work. My code is below.

#include <msp430fr5949.h>
#include <stdio.h>
#include <string.h>

#define TXD BIT2
#define RXD BIT1

char string0[255];
char string1[255];
unsigned int i; //Counter
int itterator = 0;
int itteratori = 0;
int strSize = 0;
void sendUART(char channel);
void sendUARTByte(char data, char channel);
void setup();


void main(void)
{
	setup();
	while(1) {
		volatile unsigned int i;            // volatile to prevent optimization

		        UCA0TXBUF = 'A';
		        //UCA1TXBUF = 'A';
		        strcpy(string1, "HELLO WORLD!");
		        strSize = 12;
		        //string = "HELLO WORLD!";
		        //sendUART('b');
		        i = 10000;                          // SW Delay
		        do i--;
		        while(i != 0);
	    }
}
