I downloaded the USLL map because I was bored and I followed the instructions on how to play a custom map. I put the all the map files in valvemaps. When I tried to play it through the "Run" window, I get the error "map change failed: 'USLL' not found on server"
This is command I tried to use:
C:SIERRAHalf-Lifehl.exe +map USLL
Then when I tried to run the map through the console, it said C not a valid command or something.
The tutorial told me to use the same command in the console.
