Update problem [fixed]

I'm trying to update my servers to the latest version but get the following error:

Download updated scripts Purging old staging files...

Unable to get http://www.yacs.fr/yacs/script...footprints.php. Please configure again.

All scripts

Any idea what's wrong? This happens on www.sbv54.net/sbv54 and www.sbv54.net/keva

Thanks

Jan
