danger Failed to extract file: index.php_option_com_dms_task_doc_download_id_78_

Hi,
I just did an update from 2.5.7 to 2.5.8 and got the following error message:dangerFailed to extract file: index.php_option_com_dms_task_doc_download_id_78_updater_true
My slideshows are still working, but clearly something has not worked.
Can you advise?
Alan

Hi
to use the automatic updater, you must setup your licence code
www.joomlack.fr/en/documentation/miscellaneous/202-license-code

else you can download the file from joomlack.fr and install it manually
