Problems with Google Authentication for calendar and contacts (Ver 7.0.26687.0)

I was working with no problems syncronizing Google Calendars and Contacts.
After version 7.0.26687.07 and Windows 10 upgrade, it is not working anymore.
The software keeps asking me for the credentials every time I try to check the account.
I have tried many solutions, like deleting and creating a new account.
Any ideas?
