Problem with Trusted Shops

[hups]

Hi
I just can't get this module to work in cron tab and unsure what to do. When I have set it up I get the email saying no input file selected.

In my Cron job I have inputted it as php -q /home/public_html/shop/modules/trustedshops/cron.php?secure_key=(my trusted shop id) I set it up like this as the other cron jobs I have set up start with php -q.
Also tried it as suggested on the module with http://www.(web address) trusted shop. cron etc and nothing happening.

First of all am I correct after the secure key= part do I input my trusted id?

I really could do with this working for my store so hope someone can help.

Thanks

Rob
