Ok, so far, it looks as if you are not using
MHLT, a modified version of Zoner's Half-Life Tools ["ZHLT"] (click the orange link to get it). You NEED to use ZHLT or MHLT. Also, it looks like there is a space in the name of the map, you can't do that, underscores are ok. And also, I dont know if your running it through steam correctly or not (never compiled into steam before). Well, that's my input.
