The statics in the pack aren't configured for KK correctly then. EDIT - There's a sub-folder in that zip called game data. Can I assume you actually extracted itstheLittleThings from that in to GameData? I've had a quick look at the cfgs and they seem fine at a glance, which makes me wonder whether you went and dumped game data into GameData. Because yes that'd break KK. Regardless, you need to talk to the team that made It's the Little Things.
