So upgrading should work seamlessly, but it will depend on the version you upgraded from. Were you using version 2.5 or version 2.5.x? There were 15 "patch" versions released: 2.5.1, 2.5.2, etc - all the way to 2.5.15. If you were using 2.5.6 or later, it should "just work". 2.5.6 introduced the Data Store, which moved all of the included templates and sample files, as well as all of your saved data, from the installation folder (C:\Program Files (x86)\The Tournament Director 2) to your Documents folder. If you were using 2.5.5 or earlier, you might have to copy files from the (old) installation folder over to your Documents folder. In that case, open Windows File Explorer and go to C:\Program Files (x86)\The Tournament Director 2 and copy the folders saves, templates, db, images, and sounds to your C:\Users\<your-Windows-login>\Documents\The Tournament Director 2\Data.
