Similar problem although my order went to the ACO as early as possible.
Managed to secure one via Tickets2U just before Christmas. They may still have a couple if you give them a call.
Cheers. Tickets 2 u have sold out of TR tickets, but in the end I've decided to spend a bit extra and bought the "package" deal from their sister company Travel Destinations (ferry plus camping plus entrance tickets). Rather more expensive but at least I've secured a ticket for 2010!
As of this morning Travel Destinations still 19 TR camping tickets left.
