Trouble updating Norton

My Norton is telling me that I am unprotected because my updates are too old.

 

Every time I try to fix this by running an update it comes up with the following message:

 

The following Symantec products and components are installed on your computer.

>Live update

 

Initializing...

Connecting to live update.symantecliveupdate.com

 

All of the symantec products intalled on your computer are currently up to date. Remember to check for new updates Frequently.

 

I am not too sure what to do. Any help would be greatly appreciated
