I've just managed to solve my problem with no animations by following steps:
1. Hard wipe
2. Reinstall skyrim
3. unpack SKSE from archive
4. manually drop all FNIS patches (behavior, critters and spells) to skyrim data folder
5. manually drop sexlab frame work to data folder
6. data/tools/finis for users/GenerateFNISforUsers
7. Restart SL ingame, preferably clean save.
8. Install other mods using mod organiser (dont forget XP32skeleton). Animation mods (like ZAZ, NonSexLabAanimationPack, Osex) go manually to data folder .
10. again run GenerateFNISforUsers everytime you get new animation mods or they wont kick in.
Did things in such manner because never managed to get FNIS to work from Mod Organiser platform.
Hope this helps...
