Norton 360 Identity Safe Not Workng In Internet Explorer

I do not understand why but for soem reason Identity Safe has stopped working in Internet Explorer 9. I have checked the Intenet Optins and all seems to be working fine. I have also seen that all the Symantec add-ond are enabled but still it does not work. It is working fine in Google Chrome, but for some reason not in internet explorer. Any hel gratefully received.

Thanks in advance
