I have reviewed again both your posts. If I am following your comments correctly, you converted both your 2012 FTM and Ancestry.com tree files to the next version you were testing. It also seems you did not save a backup copy of your FTM 2012 files or original Ancestry tree.
If that assessment is correct, the problem is your converting your FTM and tree files without maintaining a backup of your original FTM 2012 data and Ancestry tree. Meaning you are the problem, not FTM.
In addition, you have violated the legal non-disclosure agreement by announcing your testing of a new version of FTM and the problems you now have for which you blame FTM.
Again, I suggest you review any email you received before testing for a point of contact (an email contact) to obtain assistance. And no, I do not mean a beta test email group.
