UserSettings are no longer being placed inside the main mod folder, instead they are being placed inside the My Documents/My Games/BtS path, inside a folder of the mod's name. You need to either copy the UserSettings folder inside your new mod's folder (which brings back the issues with being in the Program Files directory, so isn't recommended if your mod is for distribution), or create a new folder of your mod's name along the My Documents path the way RevDCM 2.7's installer does, and put the UserSettings folder in there. If you use the RevDCM core for you mod, I strongly urge you to select the Source Code add one when installing 2.7, and take a look at the Install Script in there. The RevDCM install script is well commented, and checking it out should give you a good idea of how and where the different sections of the mod are installed to, and if you use 2.7 as a base the install script should be easy to convert for your mod. Of course you don't need to do this, you can just put everything back in the mod's main folder, but this isn't optimal as you run into issues with the UserSettings ini files being in program files, and public maps being invisible to the Civ4 config file.
