Welcome to the forum.
Even though your other pass is fine check your card details in My Account>payment details to make sure they are still accurate eg if your card has a new expiry date etc.

Also check you have no adblockers interfering with the browser and if possible try a different browser.
If you still have no luck have a word with live chat. You can reach them from here
