How do I use models from here in Blender?

[11th]

Took a quick look, and it loads fine for me. The model is huge, though, so when you import it you'll probably need to either downscale it or zoom out a lot, otherwise you won't see anything in the work space. (Downscale recommended since Blender's viewer seems to cut off the model after a certain point, but if you'll be using it with other models from the game you'll need to scale them all by the same amount.)
