You have not entered a valid Response Code. Please verify that you have correctly entered the response code and try again.
Causes & Solutions
A Response code must have only 20 digits (5 blocks of 4 numbers/letters). If you received your response code via email we recommend you ‘Copy (ctrl+c) & Paste (ctrl+v)’ the response code into the box provided.
If there has been a significant delay between you sending your Request code and receiving your Response code, your PC may cause the software to output a new 20 digit Request code, rendering the Response code you have been provided with unusable. If this happens we recommend you obtain a new request code by telephone, providing the latest details, and making sure you leave the activation screen on your PC running until you have obtained the new Response code.
