I am getting "This card cannot be used for this transaction" when buying an access code on the website

There are a number of possibilities and are likely an issue with your card issuer and/or PayPal. Try the following:

1. Make sure you are using the supported card type.

2. Make sure there is enough funds or credit for the transaction. 

3. Try using a different payment card.

4. Contact PayPal support at https://www.paypal.com/us/smarthelp/contact-us
