Hi! 

I'm going through the Trailhead quizzes, and I've come to the ones that say "Connect to your Developer Edition" in order to complete the quiz.  I have a Developer Edition account set up, but when I try to access it through Trailhead it gives me this message: "Houston, we have a problem... you are attempting to log into Trailhead to complete challenges with an org that isn't supported.  When you are completing Trailhead hands-on challenges, you cannot use a production or sandbox org...." Anways, I'm not sure how to complete the quizzes. (They are under Learn CRM Essentials)  Any insight is greatly appreciated!
