If you use Hive keychain installed manually, do the following:
- export your accounts (helps if you added multiple accounts)
- remove your old Hive keychain
- install Hive keychain from Chrome/Firefox addons store, depending on the browser you use
- set a locking password for Hive keychain
- import the accounts you exported at the first step
This Hive keychain installed from Chrome market.
OK, I see you found what the problem was.
