Hi, So I have a Toshiba netbook Windows7 and I bought an external CD drive for my computer since it doesn't come with one. I play PC games and I have an old game called Roller Coaster Tycoon, which I've been able to play just fine for about a year on my Toshiba. Recently all the files corrupted on it and wiped out the game so I reinstalled it and was able to play for about three months and again it worked fine. Now whenever I try playing it a message comes up saying "Please insert your RollerCoaster Tycoon CD in the following drive: F:/" but I have the game in the external drive and I don't know why it keeps coming up. I've been able to play other older PC games on my computer without this problem (like The Sims 2 and Age of Empires: The Conquerors). So I decided to install a bit newer version of RollerCoaster Tycoon, Loopy Landscapes and the same problem is happening. Is something wrong with my computer's F drive or is the game just being unresponsive?
