In reply to Stephen Horne - Rockfax:
Perhaps I owe Rockfax an apology. I've just gone to the app and it now opens! It wouldn't open back in July when I last tried it, despite numerous re-installs. Perhaps the most recent os updates have helped. Now I need to get my purchases back.
I'll update when I succeed.
Cheers
PS no idea what iPad it is. circa 2012 I think.
