unable to access identity safe

When I logged into my machine yesterday oct. 6, 2015 I could not open my vault. I read through numerous threads covering this issue over the last 18 months. I did the "fixes" ( disable fast start, uninstall/reinstsall etc. ) and I am still stuck in the "sign-in" loop. Any help is appreciated. I am running Norton 360 Premier ver. 22.5.4.24.

Thanx,
