Live Update Error

Today I tried to run LiveUpdate manually.

 

Everything updates except the Smart Definitions. It shows a red X and states that Smart Definitions X64bit did not update.

 

I turned off/on the computer and tried again, same thing: everything updates except Smart Definitions.

 

I am running NIS 2012 (19.9.0.9) on a W7.

 

This started occuring today. Is anyone else having this issue. Should I try rebooting and then running LiveUpdate?
