For those who use 3dstudiomax

Hi everybody i am using studiomax for a long time and this is the first time i face up such problem, it might seem a bit fun to you but I DONT KNOW WHAT TO DO!

I am trying to put lights in a scene and i can’t.Evey time i press the button(lights) the light appears in the middle of the plan.The problem is that i cannot move it or put it in another place.It can only be rotated.I am afraid that i activate function or sth else.

Please if you have any solution???I’M DESPARATLY!(i cannot do render)

this might help
