Is it the FTM14 update? I had an email from MacKiev a few days ago which states "Do NOT unlink your tree! If you have a linked tree on Ancestry.co.uk, the link will magically move to the new build when you install it"
Under "Technical Support" they say:
Knowledge Base. We have hundreds of helpful articles posted on our support site on a variety of topics that will be of interest to all users, and can help solve problems. To get to the knowledge base, just go to support.familytreemaker.com.
Support Requests. If you don't find what you need in the Knowledge Base articles (at support.familytreemaker.com) just click the link for “additional support” at the bottom of the page and you will see the Technical Support request form. Typically we'll be getting back to you by email in 2 days or less.
Live Chat. When you file a Support Request (see above) between the hours of 7am and 10pm GMT (7 days a week), you will have an option to have a live chat with an experienced support agent. This can be very helpful for urgent issues or those that would be easier as a discussion than an email exchange.
