Probably a bit of a long shot but i tried looking up how to install Pandora as i want to stop using nemesis but the instructions on how to do it where unclear to me. I installed it as a regular mod but am having trouble past that step.
Through Mod Manager?
1. Install it as a regular mod
2. Click on Configure Executable icons through Mod Manager ( It looks like two wheel icons in upper left corner)
3. Name it Pandora, then below click on "Binary" and find/click on Pandora Behavior Engine +.exe ( where you installed the mod)
4. Simply run executable, like SKSE or any other, through Mod Manager, tick any boxes for animation mods
It should look something like this:
I've been running it a while. It's a lot faster than Nemesis, with far less crashes.
