Is Live Update 'NO UPDATE' ????????

I am using NIS 2009 on XP sp2.I just got a problem with Live Update that it doesn't update automatically even after 6-7 hrs,even after restarting the computer!!!!!!!!!!

 

When I run Live Update manually I only receive the updates for Web Protections and everything else but Virus Definitions and Pulse Updates nowhere in the reach of LU.

 

I do not get any kind of updates naming Virus Definitions or Streaming Definitions which I was getting previously.

 

What shall I do???

If suggestion is of Reinstalling NIS.........well I have done it twice........but no joy.

 

And it is not possible for me to reinstall NIS every now and then I get  a problem, is it ?????
