So I'm new to the game. I started out with the Sidewinder then got the Hauler, then upgraded to the ASP Explorer, but very quickly realized that I could no longer up-thrust (I had no issues with first 2 ships). I first though that I mistakenly unbound the button, but I didn't. And I also realized that the up-thrust still works when I'm lifting off from a planet. But when I'm in stations or in regular space the up-thrust function seems disabled. Someone please help.
