Flight1 441 Conquest Power Problem

Hi, I just purchased the latest version (2.0) of Flight1 Conquest 441. Everything installed fine however I do have one odd problem. I try starting a flight with the Conquest sitting on the runway. The problem is that as soon as the scenario is finished loading a few seconds later I hear a little extra power on the engines and the aircraft begins to slowly move down the runway. I cannot reduce the power to idle no matter what I try. Joystick or no joystick. Can anyone offer some assistance? Thank you.
