I am a little stumped here. I was trying to do the carrier take-off training mission which use the Enterprise. I have switched the stock for one of Collins' excellent carriers and changed the model, dp,cfg,folder names of another carrier to reflect the Enterprise. The game keeps telling me it cannot find the Enterprise in the library. I then switched to the Intrepid44 and get the same response. All carriers show, except the enterprise in the regular game whenever I swap them in the missions. Any ideas why?
