Today,my Norton 360 updated to the new and improved version. Onlt 5 of my identity safe logins were saved all the others vanishe

Today,after my Norton product updated to the new and improved version all but 5 of my logins in my identity safe vanished. I did not have them backed up, I thought I had them in the safest place!  Did this happen to anyone else, and any ideas how to get them back? Norton support was no help, they did not even know that the product was upgrading!!
