Please find all the specifications and supporting browsers at prepare.tomorrowland.com .

If you are still facing issues, you can try one of the following advices: 

• Make sure you only have the event opened in only one tab of your browser. If you have the event open in multiple tabs, please close the other tabs.
• Try to close your browser and open it again.
• Refresh, or log out and try to access the event again via the website. 
• Try a different browser, preferably a most recent one. 
• Try a different device; the event is best supported on a laptop or desktop instead of a smartphone. 
• Try to clear your cache (Google Chrome and Safari).
• Use a VPN connection.

If you have followed the steps above but still experience problems, you can contact our helpdesk at nye@tomorrowland.com .
