I use Windows Live Mail 2012 because Window 10 Mail is a piece of **** compared to Live Mail 2012.

Anyway just now I rebooted my PC running Windows 10 and when I tried to sign into Windows Live Mail using my Hotmail Account it gave a message "sorry, there was a problem signing you." nothing else.  I went to Windows 10 Mail app and it works OK (even though I refuse to use it).

Windows 10 is all patched up and everything else on the PC is working fine.  I just can't sign into Live Mail 2012 using my Hotmail Account.

Anyone else having this problem or anyone know how to rectify it?
