How to get a trial version to try Cortex software?

Hello! Thank you for offering 2 week trial of Cortex software to try, but I can’t get it because on the page where payment should be verified I get message

" * You must be logged in to perform test orders, or make sure you’ve chosen “Test Payment” as your payment method.

  • We have estimated your order total as € 0,00 based on recent exchange rates. Your actual payment will be submitted as US$ 0,00"

What should I do in this case? And is it possible to receive trial version for testing?
