Due to security, access links have a one-time click through, and a 20 minute time limit.

Please check your Access Current Registration email - you may need to request a new link if the original one has expired.

You can request a new registration access email from the event organiser, otherwise you can still use the expired link to validate your details for access - how good! 

Best option is to select 'Access via email' or 'Access via mobile' where you can enter the details that match those listed on your registration and you will be sent a 5 digit verification code to gain access.
