Searching for listings

[GuernseyGirl33]

Turned on my Sky + box half an hour ago and found my programmes due to record hadn't taped and it has been saying "searching for listings" since then.  I can watch the channels ok but also get a "live pause is not available.  Call the broadcaster for assistance" message. It was working fine this morning and has only just started doing this but get the message on the bar across the bottom of the screen on every channel. Any advice or help greatly appreciated.

Have you tried restarting your Sky box by switching off at the plug for 4 minutes?

No I was worried about losing everything I have recorded as have 80% of disk space used but I can give it a go
