I found this in the Help section today.http://ancestry.custhelp.com/cgi-bin/ancestry.cfg/php/enduse...
Have any of you installed the updates they are referring to?
I have not installed the software on my computer yet so I can't confirm if anything in this article solves the problem.
I'm not so sure I want to attempt to do the other fixes they mention as I am very new to Mac.
I would love to hear feedback from those of you knee deep in this unfortunate situation.
