In the column on the right click on each of the following in order:
Ultimate Family Tree Software Tech Support & FAQ's Upgrade Information and Downloads (long way down to the next item to click) Ultimate Family Tree 2.8 Maintenance Release (PC only)
(I hope you are not using a MacIntosh, cause if you are you are out of luck.)
Download that 2.8 and install it to your 2. version of the program. It is a free upgrade. BACK UP your project(s) and Libraries, and Media files, BEFORE you install anything new.
Then if you want to configure your newer browser you can but why bother? You can go online to UFTree.com anytime you like. You no longer have to use the UFTree program to get into the UFTree website.
The 3.0 version costs, if it can be found. But the 3.0 version has some bugs which can be fixed and also has some bugs that will never be fixed. 3.0 also has a couple of enhancements.
You do know that the UFTree program is "dead"? The last company to own it announced it would not further improve the program and would provide support (ha!) until the end of the year and maybe longer. But that company has said lots of things during the past two years.
Some long-time users of UFTree have already changed to TMG (The Master Genealogist). Many of us will make that change soon.
