Vicus Scurra 0 Report post Posted May 10, 2012 Has anyone ever seen "the structure of the project is invalid. Please contact technical support" Contacting technical support does not get any help. I have an existing project with nearly 30,000 names. I try to merge a small file (the latest example having around 600 names). The error message appears. The new project has been created by importing a gedcom file. I have made some changes to places but that is about all. I have been getting this problem since upgrading to version 8 Share this post Link to post Share on other sites
