Military AI Works

I've got DXTbmp, and I know how to use it. I have repainted planes before, but nothing of amazing quality. But on to the problem, after I edit the file in my export editor, how do I reload the file? I see the "Reload after edit" button, and when I clicked it, nothing happened. Do I need to save it somewhere?

Do a normal save in the export editor before the reload after edit.

Muchos Gracias, senor.
