My OS is Windows 10 Pro 64 bit, last update today

Email desktop app is windows live mail 2012

I can receive and open emails but not type new ones.

When I click on the icon "email message" I get the error message

      "A problem occurred while trying to open this message

      A problem has occurred Please try again."

Note I am not trying to open a message but type a new one.

I have tried

"Repair"

Running as adminstrator

deleteing and rebuilding the message store

WLM will not start  with win 10 in safemode

Help please
