of 10 - Can't Log In to Nexus Mod Manager - posted in Skyrim Technical Support: I am unable to log in to the Nexus Mod Maneger client. Mine is C:\Games\Nexus Mod Manager\Skyrim\Mods If you don't know where yours are, you can reinstall NMM, not the game, to see in which directory NMM save mods.
Typically C:\Program FIles\Skyrim\Data Saved mods by NMM are saved in another directory, depending on your choice when you install NMM.
Installed mod is saved in your install game directory.
