Live Update won't fininshing installing

Hi

 

Using NIS 2009 16.5.0. 135

 

I clicked run live update downloads then starts to install says 2 of 5  and thats all the further it goes..... I Clicked cancel few minutes later get a pop up asking to make sure i want to cancel i click Yes and then get the same pop up few seconds later i click Yes and it wouldnt cancel. i clicked to restart my computer and it wouldn't restart because of Stupid Live update wouldnt stop i just had to turn off power to restart my computer. So how do i get stupid Live Update to work? and install the files on whatever files its trying to install.. 

 

when it was trying to install it wouldnt let me open Windows Mail live or any other software except for FireFox 3.5 weird,

 

Answers?

 

Thanks!
