Firstly, thank you to everyone involved in helping the rest of us mod our game and enjoy some extra dragony goodness. This thread has been really helpful, but I was still stuck. I had SKSE set up properly in MO, had the .ini file, etc, as laid out here. I finally realised that the -forcesteamloader argument has to be in the executable you are actually using. Blindingly obvious when I think about it, but it wasn't immediately clear to me. Using the argument in Mod Organizer only helps if you are launching through MO. So if anyone is following this and launching Skyrim through a desktop (or start menu) shortcut, right click on the shortcut, and press properties. Look to where it says target, and add the forcesteamloader argument there. Mine looks like this: "D:\Documents\Skyrim Files\Mod Organizer\ModOrganizer.exe" "D:\Steam\SteamApps\common\skyrim\skse_loader.exe" -forcesteamloader Hope this is useful to some. :)
