Hey, guys. Just wanted to give you a heads up that I'm in the middle of updating the add-on, enabling import and export of binary models based on MDLedit. I noticed that @Arson Hole is using the master version from GitHub. This one is not being properly tested and could be unstable. Please use version 2.1.0 from this site instead, and make sure to put all addon files under a folder named kotorblender, as @Hunters Run just said.
