I know, I know, all I do is ask questions. I can't help it. Anyway, I managed to rip Mr. Show, though I'm not sure exactly how, but now vfapi convert won't open up the d2v file! This never ends...
Answered, replied and went through this zillion times. "Search messages" button has a purpose. You very likely are missing either one .dll, are using some weird version of d2v, haven't installed the VFAPI Reader Codec before using the converter, haven't registered d2v vfapi plugin before launching converter or any mixture of these issues. Use the search Luke.
