I think I'm slowly going crazy. I set up a flight with the 737-800, everything is working as it should, I perform a pushback, start the engines, get permission to taxi, I release the parking brake,I slowly push the throttles forward and ....nothing : the plane won't budge. I can steer it but it's just not moving forward. I restart FS2004 and do the same thing with the same result : the plane is stuck. I slew it somewhere else but still nothing.Anyone any idea what to try next ?thanksMartin

You tried another (non-PMDG) plane?Bert Van Bulck
