1clickdvdcopy is only designed to reauthor then recompress already decrypted content. If you're running DVD43 Free while running 1click, then chances are DVD43Free is too old to be of use. You can use AnyDVD (current version is 5261) in the same way, so I would uninstall DVD43Free and use AnyDVD. Although it isn't free, it is actively developed (I've seen one stretch where the program was updated 3 times in about 10 days) and it's lifetime free updates, so it's worth the $39.xx and you can run it with 1click.
In the future, remember to name the movie and what version of the software and decryptor you're using. This at least will identify which they are; if the movie is newer (like "hitch"), then it's possible the decryptor can't yet handle the encryption if it's too new. In either case, include as many specifics as possible and that will help anyone reading about your difficulty to help you narrow it down and suggest solutions.
