Update: I received reply on 2/10/12 stating they were able to verify problem and asked me to try several options. (Answer Title: Repairing a damaged Family Tree Maker 2010 for Mac file. Answer Link: http://ancestry.custhelp.com/cgi-bin/ancestry.cfg/php/enduse...
Keep in mind that while these instructions are for use in the original Family Tree Maker for Mac, the instructions apply to Family Tree Maker for Mac 2 as well.)

I ran the repair and noted the differences between the two files. It didn't fix the problem, though. I sent response yesterday with screenshots.
