Hi, I've been trying to add downloaded .esm and .esp files for mod's to my plugins.txt file in my Appdata\Local\Skyrim folder. But when I load Skyrim non of these mods (the mods without such files work fine) work and when I exit Skyrim and open my plugins.txt file again, all the filenames I added are gone. Any idea's on fixing this problem? I use Windows 7 as OS.
