Help with UV mapping

Hi, I am a modder for KSP, and i am having an problem with UV mapping.
Looking on the tutorial, it said there should be a “New UV map” button, but i cant find it. Can you help? BTW, here is an image of my screen.



Thanks!

Left side in the UV window, click on “image*” and then select “new image” from the dropdown menu.
