My ability to add a signature in Acrobat XI has vanished

I have Acrobat XI Professional, and after the last update, my ability to add my scanned signature to documents has vanished.  I'm offerred Adobe cloud for $9.99 a month.  But I only need to sign 2 to 3 documents a month.   I guess I can just add my signature manually from a file every time I need it, but this is really a horrible thing to do to us.   Or have I got it wrong?
