Upgrade Amazon Simple Pay Checkout in Magento

I am using Magento 1.4.2 and customers encounter the error screen below when they try to checkout from the secure checkout area using the Amazon Simply Pay option. I need this error message to be fixed. Amazon payment buttons seems to work fine when checking out from the shopping cart.

Error message:

Input parameter signatureVersion = null is invalid. This signature version is no longer supported. Please use version 2 to sign requests.

For further information on error codes please see the Integration Guide.
