Antiphishing definitions version 20111103.002 is my latest version?

I was checking my NIS 2011 history logs and the latest antiphishing definitions version  I have shows version 20111103.002 downloaded Wednesday Nov. 2nd at 11 pm. It usually updates a couple times a day. but it hasn't shown anything in 4 days. 

What is the latest version? and if mine is not updating. what can I do to fix it.

 

I am running windows vista and NIS 2011

Thanks Kevin
