Your license is about to be renewed but you need to/want to change your payment information.
You basically just need to go on Jamendo Licensing and log in. Once there, visit your client space. Take a look at the pending order (the upcoming renewal) and click here on 'Change payment method'. It will allow you to either use another credit card or switch to payment by bank transfer.
If you previously paid by transfer and now want to use a credit card, this feature will also allow you to do so.
