nullDC crashes after starting up

[LokiGloomWalker]

Every time I try to start up nullDC, I get an error message saying that it won't run because I'm missing the following file: "d3dx9_42.dll" (without quotes). I can't access the task bar for it, so I have to get out using task manager. The one I got came with the BIOS built in, since I tried getting it from another site but it wouldn't work since winzip didn't recognize the compression method. This was the download link: http://www.theisozone.com/downloads/...nal-with-bios/

My first attempt, the one winzip didn't recognize, came from here: http://www.emulator-zone.com/doc.php...st/nulldc.html

I downloaded the one for windows.
