Apologies for the inexperience in asking this question, but is there a way of reverting from the new build 3810 to an earlier build in 4.0? I backed up when I moved from 3.0 to 4.0, but do not have a back up of the previous system in 4.0 itself. Can I just install the old upgrade version of 4.0 again? Any help will be gratefully received!
Thank you.
Thank you.
