If you are able to log into your account and want to change the credit card on file, just log into your member dashboard at https://www.warriortrading.com/login-member/ and click "Billing & Credit Card" tab and update the card there.
If you received a failed billing notice, the system will try to run the charge one more time within 24 hours. If it is past that 24 hour mark, please contact us at email@example.com to have the charge tried again and your access reactivated.
Also note that there is a way to update your billing information if you're receiving an "Access Denied" message when attempting to login. When you received the "Access Denied" message, you should be able to proceed to update your billing information through the link provided on that page. Just log in here, and then proceed to click the link located on the words "Member Site" (see below).
