I know how to convert a .blend into and xml file, and I can successfully open the .xml file with the yafray gui…but when I press “render” nothing happens. It says “rendering”, but my cpu usage is at 0%. Any comments would be appreciated! 
Is that using extractor? I use extractor, and have had no problems with it. SamtheEagle however has had some difficulty. You might try comparing notes with him.
Yes I used extractor to get it from .blend to .xml and then the yafray gui to render…
