If I remember correctly, that is part of Sierra's Copy Protection happening there. May I ask if you are using the Space Quest Collection that was released this past September? If so, there should be a guide that came with it on your computer. If you're not using that, then the answers should be online somewhere. The copy protection gets aggrivating, but there's nothing I (or anyone) else can do about it, sadly. I suggest googling the problem. The answer should be roaming the net somewhere. I know of what you speak, but I was fooling around with the game at the time, and completely skipped the scientist, I think. Then again, it was ages ago... But anyway, that is copy protection that sierra incorporated, I believe. So I suggest searching online for the answers, which shouldn't be too difficult, I imagine. I hope this helps!
