It sounds like the companion application is unable to load or correctly access mb_renderer.dll in the application installation directory for some reason. That DLL is required to interact with PDFs, so it makes sense that errors are occurring if something is causing an error in that DLL. I can't say I've ever seen that before though. Does that error occur with every PDF you've tried to use?
