in my Family Builder when I try to compare a smart match   a message box   with a  white X in a red circle  that says "An Invalid Arguement Was encountered."  I can only click on OK, or the X to close it.    It goes to the Compare view, and in my tree there is not a thing there, yet the explamation shows what I have in my tree, and the other tree, and that it all matches.  When I go back to family tree, that person is still there.
