I've been trying to get Osex working, but they just stand there, not doing anything other than making sex noises with occasional expression changes, so i tried to rerun my Fnis mod and it doesn't go through. at the bottom it tells me "ERROR(5): Access to the path 'C:\Program Files (x86)\Steam\steamapps\common\Skyrim\Data\meshes\actors\character\animations\FNIS_PCEA2\0_xp32_New_Anim_Pack' is denied." I'll be honest, this is my first personal computer, first time playing skyrim on pc, and first time modding. I've tried uninstalling and reinstalling, but i haven't tried tried installing manually. I've also been using the nexus mod organizer, which is probably a bad choice. any and all help on this subject would be appreciated.
