    jim, do make sure your signature file is ended with .html
    if you are using notepad,
    you must select the “All Files” at the “Save as Type”,
    else you will end up saving your signature file as signature.html.txt (this is still text file)

    If you can use other text editor, this problem should be able to solve easily.
