Norton Identity Safe not working with Google Chrome 50 (64 bit)

Hi

I have Google Chrome v50 64 bit on a Windows 10 machine. My Norton task bar is visible and shows my Vault is closed. The issue is that the Vault is actually open, but it isn't auto filling my passwords even though I have set the NIS settings to do so.

What is troubling is that having opened the Vault and closed the browser and then reopened it the Vault has remained open.

In addition the browser password save remains active even though I have told NIS to disable this option.

I moved to Chrome recently because IE 11 has been crashing every few minutes and Firefox doesn't work with Vault.

Any suggestions?
