After a involuntary hiatus from the sim, I tried to start it up again in the CBI Theater. Ran into a problem where it won't load because "the CIS1. gsl file cannot be read". Problem is I don't remember putting that and two other CIS. gsls named CIS2 and CIS3 in the game. I have searched and cannot find the origin of where these came from.
Does anyone recognize them and point me to where they may have originated from.
