If you're experiencing this problem, I've figured out a way around it. Basically you need to merge all of the FNIS files (creature, spells, whatever you have... don't need to for Sexy move, it works without that in it) then you install it as one. Also, I did what Dameon suggested as well with going into plugins and turned FNIS Checker from false to true. Works perfectly after that.
