Hi Juliecfc,
A warm welcome to our community 
I'm sorry to hear that you're having trouble ordering programmes from ITV via Catch Up. I'd like to help check this out for you.
Can you please get back to me with the following information:
* Name of programme (1 or 2 examples would be great)
* What time of day was this ordered?
* Was it a HD or SD version of the programme?
* Have you tried rebooting the box to refresh things over?
* Can you please specify the path you took to locate the programme via the menu?
If you can let me know I can help further.
Collette
