I have indeed, I use Filezilla, I deleted the WP-Admin and WP-Includes files as specified, copied them via FTP, copied the folders inside of WP-content to make sure I keep my themes and plug ins intact, however I did not got any overwrite warnings so copied them, copied the loose files into the root directory. But this led to either the site not working at all, fatal errors or the entire site displaying as php code.
