It appears as though you don't have the XML files installed in the proper location. There may also be an issue with the layout maps. I didn't get a clear view of that window from the video. The layout maps are part of the template files, although they may also be loaded into any finale document using the VDL Percussion Library.
Based on the video the central problem is the lack of the percussion midi maps (the XML files). These need to be copied when you upgrade to a new version. Version updates just update the current version, Finale 2014a to Finale 2014b for example. Moving from any version of finale 2014 to Finale 2014.5 is an upgrade, it was a full install. This is the same when moving to the newest version of Finale, Finale 25. The percussion midi maps will need to be copied to the same location folder for the new version. If you move them rather than copy, they will no longer exist in the previous location. They must be copied.
