They looked at my account, couldn't see a problem, so they sent an update to the box, told me to turn it off and leave it for 1/2 hour or so, then turn it on.

I did that, and initially some of the channels were back, but still missing loads, so I left it another 1/2 hour and rebooted again, then they were all ok.

Not sure what it was, but sending the update (or 'hit' as its known) seemed to fix it.
