No$Zoomer problem

I am currently playing Final Fantasy IV using No$GBA 2.6a, and of course, I had the text problem. To fix it, I was told to use No$zoomer, but when I use No$zoomer, I just get a black screen. I can hear all the sound, but there is no visual at all!
Without Zoomer, I can see everthing just fine, but there is the text problem.Anyone know how to get rid of the black screen while using No$zoomer with No$GBA 2.6a?

Try install a fresh copy. :)

After opening the ROM, try to go to no$zoomer's "Options" Tab(Press Alt+O) then "Render" (Press R) and switch from "OpenGL" to "DirectX".if Vista: Give no$zoomer admin rights and do same process^
