Wow, I wish that had been my experience! I lost days' worth of new code and data. All my projects reverted to their previous version. It's devastating!
The fact that this did not happen to you validates my memory of this not happening to me with prior updates under similar circumstances.
However, I will never update the software again before saving all open files and closing all open projects out of an abundance of caution. I'd suggest all users take this more conservative approach, as losing one's work like this is a huge and devastating pain in the neck!
Glad this did not happen to you Iode. Thanks for your reply!
