Skyrim Help. Thread

I am trying to get my mods for Skyrim on PC to work yet when I activate them and load the game and get the character(s) all set up, all they do is stand in place and not act out the mod's movements. But their faces emote and they speak like the mod was working. What am I doing wrong? I'll gladly post what mods I'm using, albiet they are mature mods.
