I don't know exactly what Ghosting does. But Bryce can't run without the Axiom system. It's a dll and set of resources (they're right there in Bryce's folder). Axiom is the system Metacreations used to be able to code for both Mac and PC at the same time. The resources are data for screens and stuff. Ghosting probably missed them or something or Bryce can't find them unless it's run from its own directory.
