Has Windows Live Mail been changed or is mine corrupted?

I use WLM as an e-mail client, mail comes through Comcast.  Toshiba Satellite Windows 7, IE10.

The Compose window has changed.  There is no longer any way to switch from plain text to rich text or vice vera.  No way to edit mail saved as drafts in the usual manner, I have to use keyboard shortcuts to cut, copy or paste.   It has become clunky and old fashioned. 

Are these changes that have been downloaded on to my computer unknown to me, or is my system corrupted?

Why, oh WHY did MS get rid of Outlook Express?  That served me SO well for 15 years .......  WLM is a poor replacement.

Oh,  and why is there no category for this?????
