Right now I am playing Half-life Blue Shift. It is fun and all, but I have messed my self up bad. There is a part where I have to jump accross some barlles and I positioned them wrong, and now I can't do it right, and I can't go back. So I looked for some cheats, but they all say place some kind of command line in my game command, or something folder. I don't even have this folder. Anybody know how to get these cheats to work?

P.S. I love everybody they are the cool.
