Q. I’m trying to pay with a credit card, but a payment error is preventing the transaction from completing.
A. Please check the error message that is shown when you try to pay. If you continue to see the same error after verifying that the credit card information and security code you entered are correct, please contact your credit card issuer.
Q. Clicking the payment URL in the e-mail doesn't take me to the credit card payment interface.
A. Copy the entire payment page URL (starting with “https:// ”) and paste it into your browser’s URL field to access the page. The URL will no longer take you to the online credit card payment interface once the 72-hour payment deadline has passed. Your registrations will be considered invalid if payment is not received before the deadline, and you will be unable to create a new registration using the same e-mail address. Please use a different e-mail address if you wish to create a new registration. If you’re unable to register, please contact the support desk by e-mail and inform them of your issue.
Q. I paid the registration fee by credit card, but the e-mail address I used to register hasn’t received any messages.
A. Please check your junk or spam folder to see if the message, sent from “no-reply@event-ope-service.com,” has been moved there. If you’re using a mobile device to receive e-mails and the app has been configured to reject messages from certain domains or senders, or messages that contain URLs, you may not be able to receive e-mails from the conference’s system. Please contact the support desk by e-mail and inform them of your issue.
Q. I haven’t received any message from the system even though I configured my e-mail app to accept messages from “event-ope-service.com.”
A. Please check your junk or spam folder to see if the message, sent from “no-reply@event-ope-service.com,” has been moved there. There may be an error in the e-mail address you used to register. Please contact the support desk by e-mail and inform them of your issue.
