I'm a newer mapper and I don't really know what I'm doing. I'm trying to make a map for Sven Coop but whenever I want to compile and test it in the, game, there is an in game error message that says: "Mod_LoadBrushModel: maps/(map name) has wrong version number (571084155 should be 30)." Also, when the compiler window opens, there is a message that says "The command failed. Windows reported the error. "The system cannot find the file specified." Do you want to continue?". Please Help.
