Hi Jessie,
I apologize for the inconvenience and for the delay in reply. Since you cannot open Windows Live Mail, you will be having issues getting the logs we need for our investigation. I suggest that you clean re-install Windows Live Mail by following either of the steps given by Helene last April 24 or by Glenda last July 12 on this thread.
If after clean re-installation fixed the issue when opening Windows Live Mail but still you are experiecing issues opening a message, I would like to reiterate the log files for our investigation. In case you clean re-install but still cannot open Windows Live Mail, kindly disable your protection software and try to open it. Kindly enable after isolating.
We'll wait for your response.
Regards,
Richard
