FrameGrabber NullPointerException

Question

I had the following code to capture an image using the webcam using Javacv. It was working without any issues but now it crashes with a NullPointerException.

Code:

public class ClientTest {

    public static void main(String[] args) {
         takeImage();

    }

    public static ImageIcon takeImage() {
        FrameGrabber grabber = null;
        IplImage img = null;
        ImageIcon image = null;
        try {
            grabber = FrameGrabber.createDefault(0);
        } catch (com.googlecode.javacv.FrameGrabber.Exception e1) {
            e1.printStackTrace();
        }
        int i = 0;
        try {
            grabber.start();

            img = grabber.grab();
            if (img != null) {
                cvFlip(img, img, 1);
            }
            // Save image
            image = new ImageIcon(img.getBufferedImage());

            grabber.flush();
            grabber.stop();
        } catch (Exception e) {
            Client.showMessage("Error taking image!");
            e.printStackTrace();

        }
        return image;
    }
}

Error:

Exception in thread "main" java.lang.NullPointerException
    at com.googlecode.javacv.FrameGrabber.create(FrameGrabber.java:95)
    at com.googlecode.javacv.FrameGrabber.createDefault(FrameGrabber.java:118)
    at Main.ClientTest.takeImage(ClientTest.java:33)
    at Main.ClientTest.main(ClientTest.java:24)

If anybody can shed some light I would greatly appreciate it, it is sort of a matter of urgency because it's part of my final year project which is due on Monday...

I just deleted all my .jar imports and reimported them. Everything seems to work now!
