wlm 2012 can not type new email get error msg “A problem occurred while trying”

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
