Blender SMD import not working? (Garry's Mod, c_arms_citizen.smd)

[Tenrys]

Hey,

I wanted to make a fun little reanimation of the CSS knife for a project on Garry's Mod using Blender, but I currently can't figure out how to import the arms into Blender?
Using [URL="https://wiki.garrysmod.com/page/Using_Viewmodel_Hands#Model_creators"]these files[/URL], Blender 2.78c (the version provided by Steam) and the latest Blender Source Tools (2.9.1), this is all I get unfortunately.

Any idea why this is happening? Thanks.

Looks like I had to zoom out.
