Live update will not register (fails)? 360

Two days ago,my live update stopped working correctly. I have Norton 360 V;21.__.__ .. What happens is I download the updates,the updates install correctly,but the warning X still appears. I have uninstalled the proper way,reinstalled the proper way,but none of this fixes the problem.. Any ideas??? I spent sometime on this yesterday with no success.(hours) 

Thank you in advance..
