Selenium Java (ATUReporter)- Getting java.lang.NullPointerException error while running the testng suite with ATUReporter - selenium

Question

I am getting java.lang.NullPointerException error while running my project which has Testng framework configured with ATUReporter
Things I have done:
Added the ATU jars in the project
Added the #Listeners({ ATUReportsListener.class, ConfigurationListener.class, MethodListener.class }) in my baseclass
Added the line System.setProperty("atu.reporter.config", "path\\ATU.properties");
Added this line to my testng file:
<listeners>
<listener class-name="atu.testng.reports.listeners.ATUReportsListener" />
<listener class-name="atu.testng.reports.listeners.ConfigurationListener" />
<listener class-name="atu.testng.reports.listeners.MethodListener" />
</listeners>
My ATU.properties file also is in the correct directory as mentioned in the Systemproperty line.
Please suggest !
Base class Sample:
#Listeners({ ATUReportsListener.class, ConfigurationListener.class, MethodListener.class })
public class test {
{
System.setProperty("atu.reporter.config", "path\\ATU.properties");
}
#Test(priority=0)
public void login()
{
OpenUrltest();
}
}

The error occured because the ATU Reports directory was manually created for the output reports generation. After deleting this directory the error got wiped out clean, so i think ATU autocreates this directory when you try to run the suite for the 1st time.
