Since Ghost should have been installed on one of your systems to create the floppy. You can easily recreate the floppy disk from your installed copy.
If the computer you are trying to restore is the one with the working copy of Ghost, then maybe you can install your copy of Ghost on the computer your posting this message from?
Lastly, you can search in the forum for the version you need, or post a request for the version you seek into an existing request thread. If someone finds the version you seek, then you can install it and use your registration number. Then create a useable floppy.
