TV Channel Changes, anyone else having problems?

Got the email saying the channels would change today, got home this evening and all I get is 'Invalid signal' I've tried searching for channels etc, but that's all I'm getting. I have the HD Box if that makes any difference. Any help appreciated, I've tried the turning off / unplugging for 39 mins as suggested in the email. Thanks.

I got the undernoted message from A2Z which with a bit of adaptation seems to have worked & I know have lots of channels (!ot sure if as many as before or more)

Essentially I went to Installation (no maintenance on my menu!) Factory Reset,Yes, English, Spain, 6900 128 QAM & then hit Manual search & it did the rest!
