umm the same thing happened to me cause it came up with
quote'
The instruction at "0x0040574d" referenced memory at "0x0202c020". The memory could not be "read".
click ok to terminate program
cancel to debug
and then it has hlcsg.exe has encountered a problem etc etc so i need to figure out whats wrong
quote'
and i figured out that it was not the compiling fault but the map itself cause it had cliffs in it that i 'borrowed' off another map but it seems those cliffs wernt made for half life so i suggest making another map and see if it works
