I'm subscribed to Creative Cloud single-app membership for Illustrator (one-year). My next renewal is due on Aug 4, 2015. But the account page says that my next payment is due on Sep 4, 2014. I would love to renew my payment since I couldn't pay for September due to insufficient funds in my band account. How do I renew my payment?
What MAY work is to go to the credit card page and do an update of your card information... even if it is the same information, that MAY trigger a payment

Otherwise, you need to contact Adobe directly
