HL Poke646 Problem Thread

Running Poke646 in Windows 7, and at the end of Map 1 you're suppsed to get to Map 2 by going through a hole in the wall near the generator. When I go through nothing happens. As flashlight doesn't seem to work, I can't see if I'm missing something in the dark "hole." I have tried also to run it under XP Compatibility, but still stuck in the hole in the wall.
