Here's the problem:
I made a simple box map with a HL monstermaker entity and monster_headcrab entity. Everything is fine. When I compile the map, (through console, not Hammer), CSG runs fine without any errors, but when I go to to run hlbsp.exe (BSP compiler), it crashes without an error. I get the whole "This program needs to close, send error report?" thing. How can I solve this or what is a common cause for this? Never had this before...
