If you have a recent backup, then you can uninstall the latest version, download the previous software, disconnect from the internet, install and then stop allowing updates as per random_nuggets post, reconnect the internet, restore your previous file and continue from there without updates. Your file will continue to confirm because you have a Perpetual Licence. If you don't have a backup, then contact FGH Tables who can restore your file to the previous version.
