A common issue with NMM, sometimes depends on the file size or current download speed delivery from Nexus, or it not recognising some modern formats etc. NMM I have used for years, but it is no longer supported. Vortex is now stable I use it all the time. Try a manual download, extract the files into your Data folder and activate through NMM, Remember to run FNIS as Selene has a lot of animations...good luck.. :mellow: Edit: I did a Skyrim SE Convert Selene Kate | Animations | Nifs | ESP video on my YouTube channel and another video for converting Arissa The Wandering Rogue. But Selene has been done in SE, and its good, recommended, just some useless info..smiles cheers Jim McCambridge
