I am using Wilco airbus evolution 1..When I take off from the ground I am unable to bank the aircraft. I am currently not using a joystick but I think it is still suppose to turn with keyboard inputs. Also after 2000 or 3000 ft after raising gear and retracting flaps, I try to click the AP1 button but on the ECAM it shows that "auto flight AP off" and sound goes off with red warning light. I cant understand the problem. I cannot engage the autopilot at all. please help....thanks
