Identity Safe doesn't appear

My problem.

I'm using Windows IE version 8 and recently I had to restart my computer and when I did and after I opened IE, the Norton toolbar appeared as normal but the identity safe text, pull down menu and everything about identity safe is gone.  I don't know how to get it back. I have restarted the browser, then the computer and still the same results.  Usually what happens is I am required to use my master password to unlock identity safe, but now - nothing.  Can anyone please help.
