Code Composer Build Errors: error#20 ADC identifiers are undefined

Hi,

I'm working on a MSP432 launchpad and trying to display an ADC value on a LCD. Now this same code (shown below) has compiled before without any problems but now, every time I try to build it or debug it, I get an error saying identifier "ADC14xxxxx" is undefined for every single instance. Eg, ADC14CTL0, ADC14CONSEQ_2, etc. Why is this happening? I didn't do anything special during the installation. All I did was make a workspace and a new project in it. There were some emulator updates but that's it. When I looked up the msp.h file in the ccsv6 folder, it says "#error "Failed to match a default include file""

Here's the code:

#include "msp.h"
#include <stdio.h>

void LCD_INIT();
void lcd_command(char cmd);
void lcd_char(char data);
void lcd_string(char data[]);
void newline();
void ADC_INIT();
int getADC();
void printADC();

int rawVolt; //unsigned long

void main(void)
{
    
    WDTCTL = WDTPW | WDTHOLD;           // Stop watchdog timer
    
    LCD_INIT();
    ADC_INIT();

    while(1)
    {
     }

}
