Can't enable creature animations

[Nithoren]

I can't get the enable creatures option to work in sexlab. It says it doesn't detect either FNIS or creature files are missing. I've gone through a bunch of forum posts and looked through the mod pages for FNIS, sexlab framework and creatures framework. I've got all the required mods for each of them and I've updated my fnis. I'm not sure what I'm missing, please help.

Did you install the SexlabCreatures file from the Sexlab download page?

Did you click the "install creatures" button in FNIS before Updating it? (or de-install button)

Newest FNIS Version?

[Nithoren]

Sexlab creatures is included in the main file as of 1.61 (according to the download page, there is also no independent download for it)

I'm not sure where that button is, but I didn't hit the de-install button

I'm on V 6.2

There's a separate FNIS for creature animations that's under "optional files" on the Nexus page, you need to have that installed as well.

I have that installed already
