Hi rodpanther ! Don't worry - just drag'n drop your poser directory from its old postion to the new one. That's it ! Just don't change any directory structure under the main poser dir, e.g. c:ProgramsCuriosLabsPoser 4 No gararantees for the ProPack or on the Mac, I garantee it works witch any Microsoft OS and Poser 4.03 Cheers, Arthur.
