Flight movement controls & Peripherals work in AC, but not in PU?

Tried to fix this without success.

My throttle worked perfectly in AC, it worked for 20 minutes in the PU, but then it failed.

When I tested throttle in AC to check, it worked fine again.

So I must have clicked something that forbids thrust despite everything else functioning.

Any input on this would be greatly welcomed.

TIA

Only thing I can think of is the Acceleration Slider. If this is near 0 your ship will not thrust well at all.

Resolved thanks to @TurinAtmos . :+1:
