EPG not working in New Zealand

Hi,
I have the latest XTi-3442 vbox running the latest firmware revision

It pickups all the freeview channels ok and I can stream them over my network to various devices.
The problem I’m having is that in the EPG most items show as “string format not supported” so I can’t actually tell what is on any of the channels.
This makes the system next to useless 🙁

I’ve contacted support and waiting for a reply.
From the little I could find online it would appear that this is to do with the EPG being encrypted. Why would they sell a box for use in NZ if doesn’t actually workConfused

thanks
Phil
