I'm having the same problem and it is driving me crazy. My toolbar in chrome will not let me sign into my norton Indentity Safe Vault. All it do is loop the sign in and Get Started window. I have logged out of norton 360 and tried to log in through the toolbar after a reboot and that does not work. To get it to work again I normally have to uninstall norton 360 at least once a week to get it to work again just to have it stop again after a few days. Please help!
