I have run into this bug unfortunately, and it's making the game unbearable. Game crashes at black market if shopkeepers are angered, or if angered inside the black market. In some instances the game crashes on any given level when shopkeepers are angered even before or without reaching the black market. Your help would be greatly appreciated as Spelunky is as important to me as food and water.
PS: Here is another thread I found on GameFaqs with others who have run into the same problem.
