To ensure that your credit card information on file is up to date, go to the PayPal website by typing the URL into your browser, log in, click on Profile, then click on Credit Cards. You can update expiration dates, billing addresses, etc., from that section.
Do not click through a link in an email asking you to update your credit card information. If there is a problem with your account, you can find out by going directly to the PayPal website and logging in. The PayPal system will usually alert you after login when there is a problem with your account.
