Suscription issues

Today my trial subscription expired. Instead of auto-renewing to a paying subscription nothing happened. I thought that it was a PayPal issue so I cancelled my subscription in order to manually re-subscribe. I cancelled my subscription successfully through the dashboard but now when I click re-subscribe ( in thehttps://cgcookie.com/dashboard/subscription page) to upgrade my membership nothing happens. Can you please help? I am really enjoying the courses and I would really like to sort this issue out asap. Thank you :)
