PayPal Pro error on live configuration: "This transaction cannot be processed due to an invalid merchant configuration"

Hi I am trying to use PayPal Pro . Test in sandbox was successful. However after publishing the form and trying to process payment I get the following error. Does PayPal Pro support Australian merchants? If yes, what could be an error?

Invalid Configuration

This transaction cannot be processed due to an invalid merchant configuration.

Unfortunately PayPal Pro is only available for US, Canada and UK.

You can use PayPal Standard or PayPal Express, but for Express you need to have your PayPal account activated for the same - this is usually as simple as sending an email to PayPal support requesting the same and they tell you if your account is already enabled to use it or if not, that they have enabled it for you.
