I too are having issues with the Sync process again. My version of FTM 2012 is telling me that I was last online at 01 Jan 0001 @ 10.30am.
My last successful Sync was at 11.49 pm on the 25 Apr 2013.
I have had major problems with FTM last year and lost over 1,000 people in my tree. I have now rebuilt it back up and added more. I have people linked to my tree and I dont want to have to go through the drama of unlinking/re-linking my trees again.
Does anyone have the same issues as myself?
