Upgraded to Windows 10 last week.  I am using Windows Live Mail for my email accounts.  Since the upgrade I have been receiving emails ok, but am not able to reply to them or even create a new email.  I get the message "A problem occurred while trying to open this message.  A problem has occurred.  Please try again".    I am using Windows Live Mail on another laptop and have no problem, although this hasn't been updated to Windows 10 yet.  Any help would be much appreciated.
