Hello Linda, yes it would be good to get a full solution, however I am not sure exactly what you mean when you say post all the settings for this module, I will try ...
I have modified the last line of the file includes/languages/english/modules/shipping/zones.php to read define('MODULE_SHIPPING_ZONES_UNDEFINED_RATE', 'FREE shipping');

Within Admin I have modules>shipping set, there are 2 zones set up. GB for local and a price, Zone 2 for rest of world and a different shipping price. Here is an example of zone 2 shipping table data 199:10, 10,000:0 ... in other words spend 200.00 or more for free shipping else pay £10.00 shipping

Unfortunately I am not sure what if any other settings I modified, I think this was it ... if you need specific settings in specific PHP files please tell me and I will find them.

Thanks again.
