norton vault not working

Hi just wondering if anyone can help me,,im having trouble with my password vault, i can sign in, but the vault sign on the toolbar dosent light up, and when i go to a website that requires my password to autofill there is no sign in box like usual to release the password,,,ive checked all my norton settings, signed in, signed out of my account, everything is on in the settings
i have uninstalled/reinstalled the toolbar, uninstalled/reinstalled chrome, restarted my pc numerous times, checked all extensions ect, 
just wondering if theres something i havent tried ?,,i havent made any pc changes to programs ect, live update is running and up to date,,any help would be appreciated, thanks
