Safe Web toolbar shows" GREY " circle with "?". Cant use IDENTITY SAFE

Im a comcast subsriber, so I get norton free with my cable serice. Comcast supposedly allows 7 computers to use thie norton service. Currently I have 3 computers with Norton running. Today I downloaded and installed the Constant Gaurd service on my PC, and now the Norton Tool bar that usually had t he safe web greeen circle and Identity safe buttons are gone!

Ive tried everything and I cant them them back and I realy need this!

 

And oh yea, the safe web and identity safe tool bar works fine on the other 3 computers I have.
