A theme consists of a .reapertheme file and generally a folder of image (.png) files - you should have both. The themes that are listed within Reaper are those that have the .reapertheme file. If that file is missing then the theme is not listed. If you have a theme folder named "xxxx" you could copy default.reapertheme to xxxx.reapertheme, then open the "xxxx" theme in Reaper. Better though, download those incomplete themes again and make sure you've got both the file and the folder of image files. HTH ---------------- Another thought - does the folder you have contain the .reapertheme file and a folder of image files? If so, drag both the file and the folder into the C:\Program Files\REAPER\ColorThemes folder (or wherever you have installed Reaper).
