Windowl Live Mail will Not let me “Reply”

When I click on "Reply" to any email I get a window labeled "Windows Live Mail" that says inside the window, "A problem occurred while trying to open this message. "A problem has occurred. Please try again" and of course "trying again" only repeats the same error. I can receive and read emails OK, I just can't "Reply" to any email from this computer. I tried repair on Windows Essentials but that didn't help. I looked for a "fixit" for Windows Live Mail but I couldn't find one. I've run CCleaner, Malwarebytes, and Microsoft Malicious Software Removal Tool and nothing was found. I don't know if this is related or not but I get a message occasionally that says "Microsoft WPD Enhanced Storage Password Driver" needs a driver and I can't find that driver any where. Does anyone know why if it's a Microsoft driver, can't Microsoft find it? Thank you.
