This sounds like a silly question, but I'm seriously at a loss here. I'm at the first computer where you get the padlock code, and I can't exit. I checked a video and it showed that there should be a monitor display, but for me it's just a gray screen with the text there.
Also, how do you save? I'd really like to enjoy this game, but I'm getting really sick of having to replay the first 15 minutes over and over due to things like this, crashes, and random drops to 1fps. It'd be much easier if I could just save right before the problem areas.
