Trying to enter my card details for payment, and Adwords is telling me my card with an expiry date March 2007, has "expired"!
Sorry for the frustration robjones2. Please take a look for a sticky from me on this.
One quick thought: if this is a newly received card replacing one which has just expired, and if you haven't yet called your bank to confirm having received the card, it would still show as expired. Is it possible that this is happening here?
