I have seen this posted previously and the solutions involved were personal to those posting. The EPG (TV Guide) on my Horizon box shows the current and next programmes only. Any previously linked recording bookings are now orphaned and I am not able to record future programmes. I have contacted customer service and they sent me a splitter for the cable. This has enabled the Horizon box to contact the UPC server and I can also use Horizon Go (re-view programmes in the last 24 hours for supported channels) but the EPG doesn’t work.
