Black mesa We-ve got hostile pre disaster

Hellow, i’m new to this forum, and i’d like to report a problem: I have Black Mesa 1.0 and I’ve installed the We-ve got hostiles pre-disaster map (version 0.2) but every time I lanch the map, the game closes directly, I’ve tried a complete check of the local files, but it doesn’t work, I find that regretable, because I really wanted to visit this place before disaster. Well, I hope someone will read me and help me solve the problem (This is a message from an English-French translator, so sorry for the many mistakes if any)
