Are you certain you are activating the mods? Do they have a check mark next to them in the list? --- He who stumbles around in darkness with a stick is blind. But he who... sticks out in darkness... is... fluorescent! - Brother Silence
My guess is something related to having NMM and Skyrim on separate drives. I know you mentioned putting it on the other drive too, but you likely put it on the SSD first and registries blah blah blah. I'm not 100% sure but that's my guess all the same. All I know is some things don't work right when you have two components in separate locations like here. --- Crimson night & Celsion moon, misfiction, not save the Player is Prayer, yes, Dance Romanesque and unfinished Romancia.
Honestly, forget NMM and download the files manually and install them with Wrye Bash. It is intimidating at first, but it will save you a lot of grief if you do more than a few mods.
The tutorials are good enough to get you started, and it is mostly drag and drop from windows explorer. About the most complicated thing you'll run into is the checkbox staying grey and the info window saying "Unrecognized Directory Structure". This is uncommon, and usually means the mod includes several incompatible options. You just open the archive and copy the options you want into a new folder (keeping the directories inside the options folders intact) and zip it back up.
What makes Wrye Bash so good is you can see exactly what a mod is writing and overwriting, and what parts of that mod are being overwritten by another. This allows you to pick and choose what parts of what mods you want to use, like a face mesh from one mod but a vampire mouth from another, for instance.
Of course, if you only have a passing interest in Skyrim, don't bother. But I've played almost 2,000 hours, and Wrye Bash is the way to go.
PS. Look up BOSS on Nexus and use it if you haven't been. It sorts many mods into most compatible order. --- I am a well-known troll. Please don't fall for my shenanigans.
