When I use Hammer to compile the map by pressing F9, it gives me an error. It reads: Could not find filesystem.dll to load. I used the Run cmd to add the map, and it added a .bsp, .pts, and a "MAP file". So when I run HL(CS), and I click New Game, and select the map from the list (it shows up), it tries to load it and gives me an error. It says, "could not find blazurban.wad." I followed a tutorial and did everything right (to my knowledge), I would love your help.
