I am having the same problems. I installed a number of mods through the Mod Manager. They are checked and activated. However, they don't work. I am running version 1.1.21.0 The "Data Files" tab on the load screen is greyed out. I don't have a "Skyrim.ini" file, I have a "Skyrim_default.ini" file as well as "High", "Low", and "Medium" ini files. I added: [Launcher] bEnableFileSelection=1 to each of the .ini files Still not working.........
