I recently did a clean install from Vista to Windows 7 and updated from FTM 2012 to FTM 2014 at the same time. I have three trees that were synced on-line that I backed up and tried to upload and relink after the install. After repeated attempts to download, merge and reestablish links, I gave up and tried uploading a new tree from my back-up. The upload was successful but I cannot sync. It hangs up when the sync gets to "Processing data from Ancestry" and closes with an error message. I have contacted Ancestry Support and Optimized my system, checked for updates, loaded and reloaded my tree, but nothing has worked. Ideally, I would like my original trees to be linked again so I do not have to re-invite the many people sharing my trees, but, now I will settle for a tree that is linked and will sync. Any suggestions?
I have Windows 7, Explorer 11, FTM 2014.
