Problem with Norton Internet Security 2010

I have the trial of Norton Internet Security 2010 and still have 28 days left, but the icon in the system tray has like a grey circle with a white line on it, as shown int he image below.

 

Also the main norton program shows a red circle with a white cross in it.
