YableX Error: Cannot launch renderer!

I’ve begun trying to learn how to use Yafray, but I’ve hit an impase. I’ve installed both YableX and Bagisas, but neither will render a xml file that I’ve made with YableX. Yable gives me the error “Cannot launch renderer” in the DOS prompt, and Bagisas gives me the error “Error. Rendered Image! None.” in a popup window. I don’t get any errors while creating the actual xml file. I have rendered a file downloaded from the Yafray site in Bagisas and it turned out fine. I’ve tried using the command line version of Yafray, but the program closes as soon as I open it. I’m using Blender 2.27 on Windows XP. Has anyone else had a problem similar to this? I have looked through the Yafray site, but couldn’t find anything similar, and I also posted a question there a few days ago, but no one has responded yet.
