Extracting Old .GHO files

I have (I Think) the latest version of Ghost Explorer V11.02.1597 and need to extract from several archives made in the early to mid-1998 era. These images were made with the DOS version of Ghost. When I try to use the newest version of Explorer I get "The Parameter is Incorrect". I need to extract files from these .GHO archives very soon. Any help would be greatly appreciated.
