Google earth crashing in c# application

Question

I'm using google earth in my C# application and it almost works fine, but occasionally I get the message

Google earth has encountered a problem ...

and supposedly it crashes (Although it's still running underneath).
what seems to be the problem here?
I thought maybe the problem is calling the google earth methods too frequently so I fixed it but still no good news...

One of the functions it crashes in is :

puvlic void clearKMLFile()
{
 try
  {
   XmlDocument mainXml = new XmlDocument();
   mainXml.Load(strKMLPath);
   string strRoot = "kml/Document/Folder";
   XmlNode ndPlaceRoot = mainXml.SelectSingleNode(strRoot);

   for (int j=0;j<5;j++)
   {
    for(int i=0;i<ndPlaceRoot.ChildNodes.Count;i++)
    {
     if(ndPlaceRoot.ChildNodes[i].Name == "Placemark")
     {
      if(ndPlaceRoot.ChildNodes[i].Attributes.Count != 0)
      {
       ndPlaceRoot.RemoceChild(ndPlaceRoot.ChildNodes[i]);
       mainXml.Save(strKMLPath);
      }
     }
    }
   }
  }
  try 
  {
   ge.OpenKmlFile(strKMLPath,1);   //this is the only Google earth API method used here
  }
  catch (Exception ex)
  {
   MessageBox.Show("An error occurred in clearring process!");
  }
}

The error message itself :

Answer 1

Finally found out what the problem was ...
For future refrence:
I was calling the ge.OpenKmlFile() method two times in a row very fast in my code, so google earth was crashing. Fixed the calls and the problem went away for now.
