When trying to compose an email message or reply/forward one  I get the message "A problem has occurred while trying to open this message".

I have windows 7 and Essentials 12.

I have tried the repair mode in Essentials via the Control panel, deleting and re-installing to no avail. I have also had error codes 0x80041161 and 0x800c0155.2 whilst trying to fix the problem.

What can you recommend?
