Auto update Hikashop Google Products Plugin

Hi,
I'm trying to set the plugin to automatically update the xml file. I want to call the file google_data_feed.xml and put it in a directory called /google-xml/.
I've put manually via FTP the file in a similar directory called /xml/, so it is visible here https://www.taichionline.it/xml/tol_google_data_feed.xml https://www.taichionline.it/xml/tol_google_data_feed.xml

This is my configuration:
FTP User Name: My user name copied and pasted from filezilla, so I'm sure it's correct
FTP Password: likewise user name
File name: tol_google_data_feed.xml
Local xml file path: I've tried "/google-xml/", "google-xml/" and with the absolute path "/web/htdocs/www.taichionline.it/home/google-xml", "/web/htdocs/www.taichionline.it/home/google-xml/"
Frequency: 30 (only for fast testing)

But nothing happens and the remote folder google-xml is alway empty.
Any suggestion?
Thanks
