on the last level, I start to sell off all my unwanted machinery to make some cash, then I get an access violation error, black screen i have to start task manager to stop the game. It only happens on the last level when I sell off machinery. I have updated my directx video card.I paid $19.95 and I have completed the game, and not gotten the trophy. Really need a patch or a refund. The graphics aren't crisp either.
