Hi everyone, This is my first time making a map, and I've been doing the tutorials here. Whenever I try and run my map, it'll start to go, but then I get an error that I cannot find the filesystem dll to load. I was wondering why I was getting this problem and how and where I can fix it. I think the biggest problem is that I'm using Steam, so it's hard for me to find many half-life files. Some help would greatly be appreciated, since I really want to make a map!
