Error 5

[Krazy07]

I installed FNIS + Flower Girls SE x onto mod organizer and my Skyrim SE loaded up fine.

I then installed FNIS Sexy Move onto it and used GenerateFNISforusers however when I tried to load up Skyrim SE after it wouldn't load and it would just display 'Failed to get process exit code: error 5'

I tried de-activating FNIS sexy move but problem stayed.

That's all the information I really understand about it so I hope someone will be able to help me.

(Also please humor me if I've made a blatant, idiotic mistake)

Solved problem. It had nothing to do with FNIS but instead it was a marriage mod I had installed that was causing me to crash or whatever
