Difficulty adding endnotes to Office

Hello friends

I installed endnote 9. When I want to add it from Office, it goes to the software and says enable synch.
It says your password is outdated. It did not get this problem when installing.

Thank you for your help.

Installing isn’t a problem, but if you want to sync, you need to register at endnote.com with a current email and password and that info needs to be in your preferences.
