Bush trips - next leg - lost control

After finishing the 1st leg (Patagonia trip) I had to stop and continue later on.
I could start later on: the screen displays ‘2 nd leg’ and the button ‘Continue’.
I did but when I push my throttle to taxi to the runway there is no reaction, while in the plane I can click the throttle and move. Then it goes. But nothing of my controller (T.Flight Hotas X) works anymore, no ailerons, no elevator, etc.
Anyone an idea?
