We recommend that you attempt the transaction again with a different card or via PayPal.
Try disabling pop-ups temporarily, and if still no success, please clear the cache on your browser and try again.
Please ensure you do not close or refresh your browser while the payment is being processed, even when the process bar is at 100%. You will need to wait for our successful transaction notification page to appear before closing your browser.
If you are still experiencing issues after this, you may need to contact your card provider.
