i have an older laptop (dell latitude D600) and can't run the game. here is the sequence of events:
installed game (on steam)
patched successfully
started game, created new character
started training level, got about 2/3 of the way (until lizards appear)
at that point, even though the game was running in windowed mode, the entire screen went black and the pc wouldn't respond to anything. it was still "alive" (hard drive activity light, caps-lock light went on when key pressed, etc.) but the display was stuck
