It's good to see you again and great to see you've settled in well
I'm sorry to read about the Channels not working on E4 and E4+1, that's never the best.
I would really like to help here and in general there aren't any outage relating to those channels. I was trying to run some specific diagnostics but would need some additional information. I've sent you a 'Private Message', you can find this by clicking on the little purple envelope near the top right of the page.
Stay in touch and get back to me when you can next
