Problem with some of Amazon categories

Hi,
  
   We recently notice issue with some of main categories & sub categories, which are not showing any products & display errors.

  Full explanation is here...http://www.a2sdeveloper.com/page-are-browse-nodes-disappearing.html

   To resolve it we have re-created main category list & enhanced error handling to search most out of Amazon.

Happy searching..
