windows live mail does not recognise my changed windows account password

For several years I have successfully run Windows Live Mail (WLM) on a latptop running Windows 8.1.  I usually use my Microsoft Account (MA) password  as the  WLM password.  I recently carried out a successful update of my  MA password but the new password is not recognised by WLM - nor is the old WLM password - so I can not send or receive WLM emails.  Grateful for advice.
