GMod Tower: Need a file.

I’ve been trying to connect to a GMod Tower server, and it needs to download some files. I’ve had to get some of my friends to send some files over becuase it doesn’t download them from the server, it says it’s downloading, but no bars appear.

And this is where I am stuck. None of my friends have this file:


And it isn’t downloading from the server, does anyone know where I can get this file from?

You need to download it from GMTTower site, not from server
