Thank you for getting back to me. After restoring the company backup and attempting to open it I get...
Error 6189, -816 and... "We're sorry but QuickBooks cannot open your company file" with "hear are some ways to fix the problem".
I have gone through those links and used the repair utilities etc as suggested on the "Tell me more" link, see below with no change.
