Asterisk - Digium Free Asterisk License Registration issue


I am using Asterisk 12 and I have downloaded required Asterisk Fax Module from Digium.

I am trying to register the Asterisk Free License, getting the below error :

There was an error with the response from the licensing server.
Status: 422 - Country must be a valid 2-letter country code
Path: /var/lib/asterisk/licenses

I have entered the correct details which at the time I have used for placed the order.

Can you please help me for this.
