Please help! Tons of errors again!

Hey guys, So I recently upgraded the version of Eclipse and now everything has errors. Essentially, stuff cannot be "resolved to a type." This applies to all lines that include textview, button, relativelayout, etc. Does anyone know how to fix this? Thanks!

''' package com.rachitagarwal.treehousecrystalball; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.widget.Button; import android.widget.TextView;

public class MainActivity extends ActionBarActivity {

private CrystalBall mCrystalBall = new CrystalBall();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Declare our View variables and assign them the Views from the layout file
    final TextView answerLabel = (TextView) findViewById(R.id.textView1);
    Button getAnswerButton = (Button) findViewById(R.id.button1);

    getAnswerButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            String answer = mCrystalBall.getAnAnswer();

            // Update the label with our dynamic answer
            answerLabel.setText(answer);
        }
    });
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

} '''

The most recent version of android has a massive bug unfortunately. I had to delete all the files and redownload the version from tree house.
