In spaceship mode I can't accelerate (but I can roll/pitch/yaw etc)

Hi,

I just installed Starry Night Pro 8 (On windows 1). In spacehip mode I tried accelating (by pressing A) and nothing happens. All the other key comannds work (pitch, roll, yaw, show/hide legend/HUD).

Is there something I can do to fix this?

Thanks,

D
