Please double-check if you are entering the barcode that belongs to the right ticket.  Be aware of the fact that you can only upgrade your 3-day weekend ticket to a 4-day weekend ticket. There are no other options as you cannot upgrade a day ticket to a 4-day weekend ticket. Bought second hand tickets via Ticketswap or did you use the Ticket Transfer Tool? Then you have new barcode on your ticket, so the ticket has to be updated in our system. Please contact Paylogic or our customer service department if you need any assistance. Make sure to add your barcode when contacting us or Paylogic so we or them can provide you with the best service.
