After subscribing to EasyBib Pro on either a monthly or yearly plan, some subscribers need to update their credit card information. The way to do this is to cancel the current subscription, and resubscribe after this subscription lapses. Don't worry, your work will not be lost when the first subscription ends!
NOTE: All subscription time will stay associated with the account and will not expire with the removal of the credit card. Your purchased subscription time will never be taken away, unless we specifically refund you money.
