Norton toolbar

I know there have been other queries about this but nothing has solved my problem. I have a Windows 8 pc and internet explorer 10. Everything has been working fine but suddenly today I cannot access the Norton toolbar. In "manage add-ons" it is disabled and no matter what I do, I cannot reactivate it. I cannot use my identy safe for log-ins and this is becoming a real problem. There must be something I can do.:smileyfrustrated:
