My problem in in the actual folder ((finder) ThisPc>LocalDisk>ProgramFiles>Steam>SteamApps>Common>Skyrim>Data) location I deleted all that was in their except the mod folders like ones that have the icon as the 3 books stacked on each other, (I deleted the files because the folder was all messy so I got the mod organizer and deleted all the extracted folders) so I thought but I must have deleted some that came with the game like it was always there and I cant undo it because they are folders and apparently you cant undo back folders idk why but you cant and the mod organizer is saying I am missing something so does anyone know how to help nvm i fixed it somehow
