Project Airbus – Talk

I have installed v3 A319cfm A320cfm with Frontier airlines liveries. When I attempt to load the aircraft a message appears, "Failed to start up the flight model." I have been trying to solve that problem but no success. Also the window in which the aircraft shows up is black. I think I have done something wrong. All other aircrafts I add do not give me this problem. I have been working on this for three days and now I need outside help. Also I have sp1a from the sdk and svc pack 2 installed.
Thanks in advance.

Problem solved . I didn't notice the 'air' file was missing. Don't know how I did that..
