You can update your CC info by logging in to the software and select the 'Your Account' link in the top right corner and click the 'Renew' button in the bottom left corner of the new window. The software will guide you through the payment and renewal process.
**Note: As we do not store credit card information directly a renewal must be processed in order to update the credit card information with our vendor. Renewing will charge your Credit Card immediately, renewing your account early (but adding the subscription time after your next renewal date). If you do not wish to be charged early you can update your credit card info at any point closer to the renewal date.
