Help Needed. Changing Shipping Module Language File but not showing changes.override?

Hello

my website www.dscrossstitchonline.co.uk

I am changing the standard parcels file from big royal mail to my hermes as they are cheaper for this size parcel.

On my other twin site .com it worked just by changed to language file and the logo for this module.

but I make the exact same changes on .co.uk and nothing different. I tried the developer tool kit and it points to the file I have changed. But it shows it unchanged even though I have ftp'd and overrided it.

If I open the file with ftp it shows my hermes. but checkout still showing standard parcels. customer test login [email protected] and password is test if you want to see.

/includes/languages/module/shipping/ would there be an override? and how could it work on 1 site but not the other. They are identical setup.

any help appreciated

HELP PLEASE

could there by an override for the shipping modules?

when i do a search with the developer tool kit from admin is still shows royal mail standard parcels. But if i ftp it it shows the myhermes details I want.

I am sure the placement it correct as have double checked many times.

can you edit a file from admin? or would I have to cpanel it that way?

BUMP

this is my shipping module file:

<?php
define('MODULE_SHIPPING_RMSTDPARCELS_TEXT_TITLE', 'My Hermes');
define('MODULE_SHIPPING_RMSTDPARCELS_TEXT_DESCRIPTION', 'My Hermes Rates. Weights in kg.');
define('MODULE_SHIPPING_RMSTDPARCELS_TEXT_WAY', '3 to 4 days Trackable. Delivery to ');
define('MODULE_SHIPPING_RMSTDPARCELS_TEXT_UNITS', 'kg');
define('MODULE_SHIPPING_RMSTDPARCELS_INVALID_ZONE', 'GB & Northern Ireland only for this service');
define('MODULE_SHIPPING_RMSTDPARCELS_UNDEFINED_RATE', 'The shipping rate cannot be determined at this time');
define('MODULE_SHIPPING_RMSTDPARCELS_TEXT_UNDERMINTOTAL', 'My Hermes is only available for orders over £');
define('MODULE_SHIPPING_RMSTDPARCELS_TEXT_OVERMAXTOTAL', 'My Hermes is only available for orders under £');

define('MODULE_SHIPPING_RMSTDPARCELS_ICON', 'myhermes.jpg');

?>

where can the website be getting the old information from still? i've done the obvious like clear cookies and tried on another computer?

please help

Old question I know, but to stop other's frustration:
The override directory is:

	includes/languages/english/modules/shipping/CUSTOM/

The changes will not show up once the order confirmation process has started.
If you go back to the shopping cart and start again the changes should show up
