The backup file cannot be restored by renaming it. It must be uncompressed using the restore command in the program. Try waiting longer. If that doesn't work...
I'm not sure it matters, but I would make sure the program is not creating new database with the same name (since it is the default)—that might conflict with the restoration of the old one. Create a new database with a different name, delete movies.pvd (if there is one), and then try restoring.
