I've been having some strange problems running this game. I got it working perfectly using DOSbox 0.74 one day and going through the setup program on the disc, but then it crashed when I tried to play it the next day. I tried reinstalling and running it a number of times with no luck. I received two error messages during this process: "Gate selector points to illegal descriptor" and "Illegal descriptor error for type 6". After these appeared, the DOSbox windows disappeared. Does anyone have suggestions as to what may be wrong?

I'm running Windows 7 on a high-spec laptop.

Thanks!
