I created a project under QE2016. Following a computer crash while waiting fixes, I downloaded a 3-day trial of QE2017 and worked on a file. When I got things fixed and re-installed QE2016 and tried to open the file I had edited under QE2017, I get the message "This Project is Locked. Changes cannot be saved.(315)"
I am running Win10 on a PC but not the Creators update.
How can I unlock the Project?
Thank you.
