Can't open Hetzchase Nailway

[Robert]

So I really want to play this Portal mod because playing the original over and over gets kind of boring

I've downloaded the files in the exact spot it said to on the other topic (steam > Steamapps > your username > Portal > Portal > Maps) but when I go to the developer console and type in "map Hetzchase_Nailway_M9Demo1" it says that the map does not exist. However, it will open the maps that I made that I saved in that spot.

Could someone help me out?
Thanks

Odd. Are you sure you placed it in the folder?
Try removing it and placing the maps in the file again.
Maybe you forgot to extract them from the .zip?
