Ok, so I had my TVDrive installed yesterday

I went for the option of moving the existing stb to my bedroom.
All seemed to be OK. The existing stb in the bedroom was up and running with all channels available (Family pack + Sky Sports).
The technician advised that it would take and hour or two for the channels to come through on the TVDrive.
No problem I though.
12 hours later and all I'm getting on the TVDrive is BBC1/2, ITV and Channel 4
The guide on the Drive suggests the other channels are available, but All I get is a blank screen.
The second stb is still working fine, with all channels.
I have re-booted, checked connections etc.
I called the fault line and they want to send someone out next week. This is all very well, but it means I'll have to be in for another day, and more importantly miss the cricket (the wife won't let me watch it in the bedroom after midnight!)
Does anyone have any idea of how to resolve this without a visit??
