The Windows live mail contact list disappeared.

 After all the sub categories disappeared my master contact list still remained but today even the master list disappeared.   No sign in was required to open Live Mail and all the solutions listed in support didn't work.

Today even the calendar disappeared.    Are the contacts and calendar gone or just hidden somewhere?

Is this an power play to make me change to Win 10 or??????
